29.2 Enhanced PWM (ePWM) Module

29.2.1 ePWM Overview

An effective PWM peripheral must be able to generate complex pulse width waveforms with minimal CPU overhead or intervention. It needs to be highly programmable and very flexible while being easy to understand and use. The ePWM unit described here addresses these requirements by allocating all needed timing and control resources on a per PWM channel basis. Cross coupling or sharing of resources has been avoided; instead, the ePWM is built up from smaller single channel modules with separate resources and that can operate together as required to form a system. This modular approach results in an orthogonal architecture and provides a more transparent view of the peripheral structure, helping users to understand its operation quickly.

As already described in Section 29.1.3, the letter x within a signal or module name is used to indicate a generic ePWM instance on a device. For example, output signals EPWMxA and EPWMxB refer to the output signals from the ePWMx instance. Thus, EPWM1A and EPWM1B belong to ePWM1, EPWM2A and EPWM2B belong to ePWM2, etc.

The ePWM module represents one complete PWM channel composed of two PWM outputs: EPWMxA and EPWMxB. A given ePWM module functionality can be extended with the so called High-Resolution Pulse Width modulator. Refer to the Section 29.1.3, to determine which ePWM instances include the HRPWM feature. The HRPWM functionalities are described in Section 29.2.45. Each ePWM module is indicated by a numerical value starting with 1. For example ePWM1 is the first instance, the ePWM2 is the second instance in the device, etc. The ePWMx indicates any instance.

As also described in Section 29.1.3.1.2, the ePWM modules are chained together via a clock synchronization scheme that allows them to operate as a single system when required. Additionally, the PWMSSn integration allows this synchronization scheme to be extended to the capture peripheral modules (eCAP). The number of modules is device-dependent and based on target application needs. Modules can also operate stand-alone.

Each ePWM module supports the following features:

  • Dedicated 16-bit time-base counter with period and frequency control
  • Two PWM outputs (EPWMxA and EPWMxB) that can be used in the following configurations:
    • Two independent PWM outputs with single-edge operation
    • Two independent PWM outputs with dual-edge symmetric operation
    • One independent PWM output with dual-edge asymmetric operation
  • Asynchronous override control of PWM signals through software.
  • Programmable phase-control support for lag or lead operation relative to other ePWM modules.
  • Hardware-locked (synchronized) phase relationship on a cycle-by-cycle basis.
  • Dead-band generation with independent rising and falling edge delay control.
  • Programmable trip zone allocation of both cycle-by-cycle trip and one-shot trip on fault conditions.
  • A trip condition can force either high, low, or high-impedance state logic levels at PWM outputs.
  • Programmable event prescaling minimizes CPU overhead on interrupts.
  • PWM chopping by high-frequency carrier signal, useful for pulse transformer gate drives.

Each ePWM module is connected to the input/output signals shown in Figure 29-5. The signals are described in detail in subsequent sections.

The order in which the ePWM modules are connected may differ from what is shown in Figure 29-5. See Section 29.1.3.1.2 for the actual synchronization scheme implemented in the device. Each ePWM module consists of seven submodules and is connected within a system via the signals shown in Figure 29-6.

AM571x Submodules and Signal Connections for an ePWM ModuleFigure 29-6 Submodules and Signal Connections for an ePWM Module

Figure 29-7 shows more internal details of a single ePWM module. The main signals used by the ePWM module are:

  • PWM output signals (EPWMxA and EPWMxB). The PWM output signals are made available external to the device through the GPIO peripheral described in the system control and interrupts guide for your device.
  • Trip-zone signals ( TZ0 to TZk-1). These k input signals alert the ePWM module of an external fault condition. Each module on a device can be configured to either use or ignore any of the trip-zone signals. The trip-zone signal can be configured as an asynchronous input through the GPIO peripheral.
    Note:

    According to the device ePWMx (where x= 1to 3) trip zone i/f implementation, the number of input signals implemented is k=1, which means ONLY the ePWMx TZ0 input is available at chip level. Refer to the Section 29.1.3, for details on trip zone input implementation.

  • Time-base synchronization input (EPWMxSYNCI) and output (EPWMxSYNCO) signals. The synchronization signals daisy chain the ePWM modules together. Each module can be configured to either use or ignore its synchronization input. The clock synchronization input and output signal are brought out to pins only for ePWM1 (ePWM module #1). The synchronization output for ePWM3 (EPWM3SYNCO) is also connected to the eCAP1SYNCI of the first enhanced capture module (eCAP1).
  • Peripheral Bus. The peripheral bus is 32-bits wide and allows both 16-bit and 32-bit writes to the ePWM register file.

Figure 29-7 also shows the key internal submodule interconnect signals. Each submodule is described in Section 29.2.2.

29.2.3 ePWM Submodule Features

Table 29-15 lists the eight key submodules together with a list of their main configuration parameters. For example, if you need to adjust or control the duty cycle of a PWM waveform, then you should see the counter-compare submodule in Section 29.2.14 for relevant details.

29.2.5 Proper ePWM Interrupt Initialization Procedure

When the ePWM peripheral clock is enabled it may be possible that interrupt flags may be set due to spurious events due to the ePWM registers not being properly initialized. The proper procedure for initializing the ePWM peripheral is:

  1. Disable global interrupts (CPU INTM flag)
  2. Disable ePWM interrupts
  3. Initialize peripheral registers
  4. Clear any spurious ePWM flags
  5. Enable ePWM interrupts
  6. Enable global interrupts

29.2.6 ePWM Time-Base (TB) Submodule

Each ePWM module has its own time-base submodule that determines all of the event timing for the ePWM module. Built-in synchronization logic allows the time-base of multiple ePWM modules (ePWMx) to work together as a single system. Figure 29-8 illustrates the time-base module's place within the ePWM.

AM571x ePWM Time-Base Submodule Block DiagramFigure 29-8 ePWM Time-Base Submodule Block Diagram

29.2.7 Purpose of the ePWM Time-Base Submodule

You can configure the time-base submodule for the following:

  • Specify the ePWMx time-base counter (TBCNT) frequency or period in the EPWM_TBCNT register to control how often events occur.
  • Manage time-base synchronization with other ePWMx modules.
  • Maintain a phase relationship with other ePWMx modules.
  • Set the time-base counter to count-up, count-down, or count-up-and-down mode.
  • Generate the following events:
    • TBCNT = PRD: Time-base counter (EPWM_TBCNT register) equal to the specified period in EPWM_TBPRD register (i.e. TBCNT = TBPRD) .
    • TBCNT = 0: Time-base counter equal to zero (TBCNT = 0000h).
  • Configure the rate of the time-base clock; a prescaled version of the CPU system clock (SYSCLKOUT). This allows the time-base counter to increment/decrement at a slower rate.

29.2.8 Controlling and Monitoring the ePWM Time-Base Submodule

Table 29-16 lists the registers used to control and monitor the time-base submodule.

(1) This register is available only on ePWM instances that include the high-resolution extension (HRPWM). On ePWM modules that do not include the HRPWM, this location is reserved. See Section 29.1.3 to determine which ePWM instances include this feature.

Figure 29-9 shows the critical signals and registers of the time-base submodule. Table 29-17 provides descriptions of the key signals associated with the time-base submodule.

AM571x ePWM Time-Base Submodule Signals and RegistersFigure 29-9 ePWM Time-Base Submodule Signals and Registers
Table 29-17 ePWM Key Time-Base Signals
SignalDescription
EPWMxSYNCITime-base synchronization input.
Input pulse used to synchronize the time-base counter with the counter of ePWM module earlier in the synchronization chain. An ePWM peripheral can be configured to use or ignore this signal. For the first ePWM module (EPWM1) this signal comes from a device pin . For subsequent ePWM modules this signal is passed from another ePWM peripheral. For example, EPWM2SYNCI is generated by the ePWM1 peripheral and the EPWM3SYNCI is generated by ePWM2. See Section 29.2.11 for information on the synchronization order of a particular device.
EPWMxSYNCOTime-base synchronization output.
This output pulse is used to synchronize the counter of an ePWM module later in the synchronization chain. The ePWM module generates this signal from one of three event sources:
  1. EPWMxSYNCI (Synchronization input pulse)
  2. TBCNT = 0: The time-base counter (register EPWM_TBCNT) equal to zero (TBCNT = 0000h).
  3. TBCNT = CMPB: The time-base counter (register EPWM_TBCNT) equal to the counter-compare B register - EPWM_CMPB (i.e. bitfield TBCNT = bitfield CMPB) .
TBCNT = PRDTime-base counter equal to the specified period.
This signal is generated whenever the counter value is equal to the active period register value. That is when TBCNT = TBPRD.
TBCNT = 0Time-base counter equal to zero.
This signal is generated whenever the counter value is zero. That is when TBCNT equals 0000h.
TBCNT = CMPBTime-base counter equal to active counter-compare B register (TBCNT = CMPB).
This event is generated by the counter-compare submodule and used by the synchronization out logic.
CTR_dirTime-base counter direction.
Indicates the current direction of the ePWM's time-base counter. This signal is high when the counter is increasing and low when it is decreasing.
CTR_maxTime-base counter equal max value. (TBCNT = FFFFh)
Generated event when the EPWM_TBCNT value reaches its maximum value. This signal is only used only as a status bit.
TBCLKTime-base clock.
This is a prescaled version of the system clock - SYSCLKOUT(1) and is used by all submodules within the ePWMn. This clock determines the rate at which time-base counter increments or decrements.
(1) The system clock - SYSCLKOUT is the ePWM functional clock derived from the PWMSSn gateable interface and functional clock PWMSSn_GICLK, described in Section 29.1.3.

29.2.9 Calculating PWM Period and Frequency

The frequency of PWM events is controlled by the time-base period (EPWM_TBPRD) register and the mode of the time-base counter. Figure 29-10 shows the period (Tpwm) and frequency (Fpwm) relationships for the up-count, down-count, and up-down-count time-base counter modes when when the period is set to 4 (EPWM_TBPRD register bitfield TBPRD = 0x4). The time increment for each step is defined by the time-base clock (TBCLK) which is a prescaled version of the system clock (SYSCLKOUT).

The time-base counter has three modes of operation selected by the time-base control register (EPWM_TBCTL):

  • Up-Down-Count Mode: In up-down-count mode, the time-base counter starts from zero and increments until the period (TBPRD) value is reached. When the period value is reached, the time-base counter then decrements until it reaches zero. At this point the counter repeats the pattern and begins to increment.
  • Up-Count Mode: In this mode, the time-base counter starts from zero and increments until it reaches the value in the period register (TBPRD). When the period value is reached, the time-base counter resets to zero and begins to increment once again.
  • Down-Count Mode: In down-count mode, the time-base counter starts from the period (TBPRD) value and decrements until it reaches zero. When it reaches zero, the time-base counter is reset to the period value and it begins to decrement once again.

29.2.10 ePWM Time-Base Period Shadow Register

The time-base period register (EPWM_TBPRD) has a shadow register. Shadowing allows the register update to be synchronized with the hardware. The following definitions are used to describe all shadow registers in the ePWM module:

  • Active Register: The active register controls the hardware and is responsible for actions that the hardware causes or invokes.
  • Shadow Register: The shadow register buffers or provides a temporary holding location for the active register. It has no direct effect on any control hardware. At a strategic point in time the shadow register's content is transferred to the active register. This prevents corruption or spurious operation due to the register being asynchronously modified by software.

The memory address of the shadow period register is the same as the active register. Which register is written to or read from is determined by the EPWM_TBCTL[3] PRDLD bit. This bit enables and disables the EPWM_TBPRD shadow register as follows:

  • Time-Base Period Shadow Mode: The EPWM_TBPRD shadow register is enabled when EPWM_TBCTL[3] PRDLD = 0. Reads from and writes to the EPWM_TBPRD memory address go to the shadow register. The shadow register contents are transferred to the active register (EPWM_TBPRD (Active) ← EPWM_TBPRD (shadow)) when the time-base counter (register (EPWM_TBCNT) equals zero (TBCNT = 0000h). By default the EPWM_TBPRD shadow register is enabled.
  • Time-Base Period Immediate Load Mode: If immediate load mode is selected (EPWM_TBCTL[3] PRDLD = 1), then a read from or a write to the TBPRD memory address goes directly to the active register.

29.2.11 ePWM Time-Base Counter Synchronization

A time-base synchronization scheme connects all of the ePWM modules on a device. Each ePWM module has a synchronization input (EPWMxSYNCI) and a synchronization output (EPWMxSYNCO). The input synchronization for the first instance (ePWM1) comes from an external pin . For the device ePWM environment sync pin details refer to the Section 29.1.2. The possible synchronization connections for the remaining ePWM modules is shown in Figure 29-11.

AM571x ePWM Time-Base Counter Synchronization Scheme 1Figure 29-11 ePWM Time-Base Counter Synchronization Scheme 1

Each ePWM module can be configured to use or ignore the synchronization input. If the EPWM_TBCTL[2] PHSEN bit is set, then the time-base counter (TBCNT) of the ePWM module (register EPWM_TBCNT) will be automatically loaded with the phase register (EPWM_TBPHS) contents when one of the following conditions occur:

  • EPWMxSYNCI: Synchronization Input Pulse: The value of the phase register is loaded into the counter register when an input synchronization pulse is detected (EPWM_TBPHS → EPWM_TBCNT). This operation occurs on the next valid time-base clock (TBCLK) edge.
  • Software Forced Synchronization Pulse: Writing a 1 to the EPWM_TBCTL[6] SWFSYNC control bit invokes a software forced synchronization. This pulse is ORed with the synchronization input signal, and therefore has the same effect as a pulse on EPWMxSYNCI.

This feature enables the ePWM module to be automatically synchronized to the time base of another ePWM module. Lead or lag phase control can be added to the waveforms generated by different ePWM modules to synchronize them. In up-down-count mode, the EPWM_TBCTL[13] PHSDIR bit configures the direction of the time-base counter immediately after a synchronization event. The new direction is independent of the direction prior to the synchronization event. The TBPHS bit is ignored in count-up or count-down modes. See Figure 29-12 through Figure 29-15 for examples.

Clearing the EPWM_TBCTL[2] PHSEN bit configures the ePWM to ignore the synchronization input pulse. The synchronization pulse can still be allowed to flow-through to the EPWMxSYNCO and be used to synchronize other ePWM modules. In this way, you can set up a master time-base (for example, ePWM1) and downstream modules (ePWM2 - ePWMx) may elect to run in synchronization with the master.

29.2.12 Phase Locking the Time-Base Clocks of Multiple ePWM Modules

As already described in the Section 29.1.3.1.3, PWMSS1_TBCLKEN through PWMSS3_TBCLKEN bits in the CTRL_CORE_CONTROL_IO_2 register of the device Core Control Module can be used to individually control or globally synchronize the time-base clocks of all enabled ePWM modules on a device. When all PWMSSN_TBCLKEN (where n = 1 to 3) bits are set to 0b0, the time-base clocks of all ePWMx (where x = 1 to 3) modules are stopped (default). When all PWMSSn_TBCLKEN bits are simultaneously set in SW to 0b1, all ePWMx modules (x = 1 to 3) time-base clocks are started with the rising edge of TBCLK aligned. For perfectly synchronized TBCLKs, the prescaler bits in the EPWM_TBCTL register of each ePWM module must be set identically. The proper procedure for enabling the ePWM clocks is as follows:

  1. Enable the ePWM module clocks.
  2. Set PWMSSn_TBCLKEN = 0. This will stop the time-base clock within any enabled ePWMx module.
  3. Configure the prescaler values and desired ePWM modes per each involved ePWMx.
  4. Simultaneously set bits PWMSSn_TBCLKEN to 0b1 (where n = 1 to 3) 1.

29.2.13 ePWM Time-Base Counter Modes and Timing Waveforms

The time-base counter operates in one of four modes:

  • Up-count mode which is asymmetrical.
  • Down-count mode which is asymmetrical.
  • Up-down-count which is symmetrical.
  • Frozen where the time-base counter is held constant at the current value.

To illustrate the operation of the first three modes, Figure 29-12 to Figure 29-15 show when events are generated and how the time-base responds to an EPWMxSYNCI signal.

29.2.14 ePWM Counter-Compare (CC) Submodule

Figure 29-16 illustrates the counter-compare submodule within the ePWM. Figure 29-17 shows the basic structure of the counter-compare submodule.

29.2.15 Purpose of the ePWM Counter-Compare Submodule

The counter-compare submodule takes as input the time-base counter value. This value is continuously compared to the counter-compare A (EPWM_CMPA) and counter-compare B (EPWM_CMPB) registers. When the time-base counter is equal to one of the compare registers, the counter-compare unit generates an appropriate event.

The counter-compare submodule:

  • Generates events based on programmable time stamps using the EPWM_CMPA and EPWM_CMPB registers
    • TBCNT = CMPA: Time-base counter equals counter-compare A register (TBCNT = CMPA).
    • TBCNT = CMPB: Time-base counter equals counter-compare B register (TBCNT = CMPB)
  • Controls the PWM duty cycle if the action-qualifier submodule is configured appropriately
  • Shadows new compare values to prevent corruption or glitches during the active PWM cycle

Table 29-18 lists the registers used to control and monitor the counter-compare submodule. Table 29-19 lists the key signals associated with the counter-compare submodule.

29.2.17 Operational Highlights for the ePWM Counter-Compare Submodule

The counter-compare submodule is responsible for generating two independent compare events based on two compare registers:

  1. TBCNT = CMPA: Time-base counter equal to counter-compare A register (EPWM_TBCNT = EPWM_CMPA).
  2. TBCNT = CMPB: Time-base counter equal to counter-compare B register (TBCNT = CMPB).

For up-count or down-count mode, each event occurs only once per cycle. For up-down-count mode each event occurs twice per cycle, if the compare value is between 0000h and TBPRD; and occurs once per cycle, if the compare value is equal to 0000h or equal to TBPRD. These events are fed into the action-qualifier submodule where they are qualified by the counter direction and converted into actions if enabled. Refer to Section 29.2.20 for more details.

The counter-compare registers EPWM_CMPA and EPWM_CMPB each have an associated shadow register. Shadowing provides a way to keep updates to the registers synchronized with the hardware. When shadowing is used, updates to the active registers only occurs at strategic points. This prevents corruption or spurious operation due to the register being asynchronously modified by software. The memory address of the active register and the shadow register is identical. Which register is written to or read from is determined by the EPWM_CMPCTL[4] SHDWAMODE and EPWM_CMPCTL[6] SHDWBMODE bits. These bits enable and disable the EPWM_CMPA shadow register and EPWM_CMPB shadow register respectively. The behavior of the two load modes is described below:

  • Shadow Mode: The shadow mode for the EPWM_CMPA is enabled by clearing the EPWM_CMPCTL[4] SHDWAMODE bit and the shadow register for CMPB is enabled by clearing the EPWM_CMPCTL[6] SHDWBMODE bit. Shadow mode is enabled by default for both EPWM_CMPA and EPWM_CMPB.

    If the shadow register is enabled then the content of the shadow register is transferred to the active register on one of the following events:

    • TBCNT = PRD: Time-base counter equal to the period (TBCNT = TBPRD).
    • TBCNT = 0: Time-base counter equal to zero (TBCNT = 0000h)
    • Both TBCNT = PRD and TBCNT = 0

    Which of these three events is specified by the EPWM_CMPCTL[1:0] LOADAMODE and EPWM_CMPCTL[3:2] LOADBMODE register bits. Only the active register contents are used by the counter-compare submodule to generate events to be sent to the action-qualifier.

  • Immediate Load Mode: If immediate load mode is selected (EPWM_TBCTL[4] SHDWAMODE = 1 or EPWM_TBCTL[6] SHDWBMODE = 1), then a read from or a write to the register will go directly to the active register.

29.2.18 ePWM Count Mode Timing Waveforms

The counter-compare module can generate compare events in all three count modes:

  • Up-count mode: used to generate an asymmetrical PWM waveform.
  • Down-count mode: used to generate an asymmetrical PWM waveform.
  • Up-down-count mode: used to generate a symmetrical PWM waveform.

To best illustrate the operation of the first three modes, the timing diagrams in Figure 29-18 to Figure 29-21 show when events are generated and how the EPWMxSYNCI signal interacts.

AM571x ePWM Counter-Compare Event Waveforms in Up-Count Mode
An EPWMxSYNCI external synchronization event can cause a discontinuity in the TBCNT count sequence. This can lead to a compare event being skipped. This skipping is considered normal operation and must be taken into account.

29.2.19 ePWM Action-Qualifier (AQ) Submodule

Figure 29-22 shows the action-qualifier (AQ) submodule (see shaded block) in the ePWM system. The action-qualifier submodule has the most important role in waveform construction and PWM generation. It decides which events are converted into various action types, thereby producing the required switched waveforms at the EPWMxA and EPWMxB outputs.

AM571x ePWM Action-Qualifier SubmoduleFigure 29-22 ePWM Action-Qualifier Submodule

29.2.20 Purpose of the ePWM Action-Qualifier Submodule

The action-qualifier submodule is responsible for the following:

  • Qualifying and generating actions (set, clear, toggle) based on the following events:
    • TBCNT = PRD: Time-base counter equal to the period (TBCNT = TBPRD)
    • TBCNT = 0: Time-base counter equal to zero (TBCNT = 0000h)
    • TBCNT = CMPA: Time-base counter equal to the counter-compare A register (TBCNT = CMPA)
    • TBCNT = CMPB: Time-base counter equal to the counter-compare B register (TBCNT = CMPB)
  • Managing priority when these events occur concurrently
  • Providing independent control of events when the time-base counter is increasing and when it is decreasing.

29.2.21 Controlling and Monitoring the ePWM Action-Qualifier Submodule

Table 29-20 lists the registers used to control and monitor the action-qualifier submodule.

The action-qualifier submodule is based on event-driven logic. It can be thought of as a programmable cross switch with events at the input and actions at the output, all of which are software controlled via the set of registers shown in Figure 29-23. The possible input events are summarized again in Table 29-21.

Software forced eventAsynchronous event initiated by software

The software forced action is a useful asynchronous event. This control is handled by registers EPWM_AQSFRC and EPWM_AQCSFRC.

The action-qualifier submodule controls how the two outputs EPWMxA and EPWMxB behave when a particular event occurs. The event inputs to the action-qualifier submodule are further qualified by the counter direction (up or down). This allows for independent action on outputs on both the count-up and count-down phases.

The possible actions imposed on outputs EPWMxA and EPWMxB are:

  • Set High: Set output EPWMxA or EPWMxB to a high level.
  • Clear Low: Set output EPWMxA or EPWMxB to a low level.
  • Toggle: If EPWMxA or EPWMxB is currently pulled high, then pull the output low. If EPWMxA or EPWMxB is currently pulled low, then pull the output high.
  • Do Nothing: Keep outputs EPWMxA and EPWMxB at same level as currently set. Although the "Do Nothing" option prevents an event from causing an action on the EPWMxA and EPWMxB outputs, this event can still trigger interrupts. See the event-trigger submodule description in Section 29.2.41 for details.

Actions are specified independently for either output (EPWMxA or EPWMxB). Any or all events can be configured to generate actions on a given output. For example, both TBCNT = CMPA and TBCNT = CMPB can operate on output EPWMxA. All qualifier actions are configured via the control registers found at the end of this section.

For clarity, the drawings in this chapter use a set of symbolic actions. These symbols are summarized in Figure 29-24. Each symbol represents an action as a marker in time. Some actions are fixed in time (zero and period) while the CMPA and CMPB actions are moveable and their time positions are programmed via the counter-compare A and B registers, respectively. To turn off or disable an action, use the "Do Nothing option"; it is the default at reset.

29.2.22 ePWM Action-Qualifier Event Priority

It is possible for the ePWM action qualifier to receive more than one event at the same time. In this case events are assigned a priority by the hardware. The general rule is events occurring later in time have a higher priority and software forced events always have the highest priority. The event priority levels for up-down-count mode are shown in Table 29-22. A priority level of 1 is the highest priority and level 7 is the lowest. The priority changes slightly depending on the direction of TBCNT.

Table 29-22 ePWM Action-Qualifier Event Priority for Up-Down-Count Mode
Priority LevelEvent if TBCNT is Incrementing
TBCNT = 0 up to TBCNT = TBPRD		Event if TBCNT is Decrementing
TBCNT = TBPRD down to TBCNT = 1
1 (Highest)Software forced eventSoftware forced event
2Counter equals CMPB on up-count (CBU)Counter equals CMPB on down-count (CBD)
3Counter equals CMPA on up-count (CAU)Counter equals CMPA on down-count (CAD)
4Counter equals zeroCounter equals period (TBPRD in EPWM_TBPRD active register)
5Counter equals CMPB on down-count (CBD) (1)Counter equals CMPB on up-count (CBU) (1)
6 (Lowest)Counter equals CMPA on down-count (CAD) (1)Counter equals CMPA on up-count (CBU) (1)
(1) To maintain symmetry for up-down-count mode, both up-events (CAU/CBU) and down-events (CAD/CBD) can be generated for TBPRD. Otherwise, up-events can occur only when the counter is incrementing and down-events can occur only when the counter is decrementing.

Table 29-23 shows the action-qualifier priority for up-count mode. In this case, the counter direction is always defined as up and thus down-count events will never be taken.

1 (Highest)Software forced event
2Counter equal to period (TBPRD)
3Counter equal to CMPB on up-count (CBU)
4Counter equal to CMPA on up-count (CAU)

Table 29-24 shows the action-qualifier priority for down-count mode. In this case, the counter direction is always defined as down and thus up-count events will never be taken.

It is possible to set the compare value greater than the period. In this case the action will take place as shown in Table 29-25.

If CMPA/CMPB > TBPRD, then the event will not occur.
Down-Count ModeNever occurs.If CMPA/CMPB < TBPRD, the event will occur on a compare match (TBCNT = CMPA or CMPB).
If CMPA/CMPB ≥ TBPRD, the event will occur on a period match (TBCNT = TBPRD).
Up-Down-Count ModeIf CMPA/CMPB < TBPRD and the counter is incrementing, the event occurs on a compare match (TBCNT = CMPA or CMPB).If CMPA/CMPB < TBPRD and the counter is decrementing, the event occurs on a compare match (TBCNT = CMPA or CMPB).
If CMPA/CMPB is ≥ TBPRD, the event will occur on a period match (TBCNT = TBPRD).If CMPA/CMPB ≥ TBPRD, the event occurs on a period match (TBCNT = TBPRD).

29.2.23 Waveforms for Common ePWM Configurations

Note:

The waveforms in this chapter show the ePWMs behavior for a static compare register value. In a running system, the active compare registers (EPWM_CMPA and EPWM_CMPB) are typically updated from their respective shadow registers once every period. The user specifies when the update will take place; either when the time-base counter reaches zero or when the time-base counter reaches period. There are some cases when the action based on the new value can be delayed by one period or the action based on the old value can take effect for an extra period. Some PWM configurations avoid this situation. These include, but are not limited to, the following:

Use up-down-count mode to generate a symmetric PWM:

Use up-down-count mode to generate an asymmetric PWM:

  • To achieve 50%-0% asymmetric PWM use the following configuration: Load EPWM_CMPA/EPWM_CMPB on period and use the period action to clear the PWM and a compare-up action to set the PWM. Modulate the compare value from 0 to TBPRD to achieve 50%-0% PWM duty.

When using up-count mode to generate an asymmetric PWM:

  • To achieve 0-100% asymmetric PWM use the following configuration: Load EPWM_CMPA/EPWM_CMPB on TBPRD. Use the Zero action to set the PWM and a compare-up action to clear the PWM. Modulate the compare value from 0 to TBPRD+1 to achieve 0-100% PWM duty.

Figure 29-25 shows how a symmetric PWM waveform can be generated using the up-down-count mode of the TBCNT. In this mode 0%-100% DC modulation is achieved by using equal compare matches on the up count and down count portions of the waveform. In the example shown, CMPA is used to make the comparison. When the counter is incrementing the CMPA match will pull the PWM output high. Likewise, when the counter is decrementing the compare match will pull the PWM signal low. When CMPA = 0, the PWM signal is low for the entire period giving the 0% duty waveform. When EPWM_CMPA = EPWM_TBPRD, the PWM signal is high achieving 100% duty.

When using this configuration in practice, if you load CMPA/CMPB on zero, then use CMPA/CMPB values greater than or equal to 1. If you load CMPA/CMPB on period, then use CMPA/CMPB values less than or equal to TBPRD-1. This means there will always be a pulse of at least one TBCLK cycle in a PWM period which, when very short, tend to be ignored by the system.

The PWM waveforms in Figure 29-26 through Figure 29-31 show some common action-qualifier configurations. Some conventions used in the figures are as follows:

  • TBPRD, CMPA, and CMPB refer to the value written in their respective registers (EPWM_TBPRD, EPWM_CMPA, and EPWM_CMPB). The active register, not the shadow register, is used by the hardware.
  • CMPx, refers to either CMPA or CMPB.
  • EPWMxA and EPWMxB refer to the output signals from ePWMx
  • Up-Down means Count-up-and-down mode, Up means up-count mode and Dwn means down-count mode
  • Sym = Symmetric, Asym = Asymmetric

29.2.24 ePWM Dead-Band Generator (DB) Submodule

Figure 29-32 illustrates the dead-band generator submodule within the ePWM module.

AM571x Dead-Band Generator SubmoduleFigure 29-32 Dead-Band Generator Submodule

29.2.25 Purpose of the ePWM Dead-Band Submodule

The "Action-qualifier (AQ) Module" section discussed how it is possible to generate the required dead-band by having full control over edge placement using both the CMPA and CMPB resources of the ePWM module. However, if the more classical edge delay-based dead-band with polarity control is required, then the dead-band generator submodule should be used.

The key functions of the dead-band generator submodule are:

  • Generating appropriate signal pairs (EPWMxA and EPWMxB) with dead-band relationship from a single EPWMxA input
  • Programming signal pairs for:
    • Active high (AH)
    • Active low (AL)
    • Active high complementary (AHC)
    • Active low complementary (ALC)
  • Adding programmable delay to rising edges (RED)
  • Adding programmable delay to falling edges (FED)
  • Can be totally bypassed from the signal path (note dotted lines in diagram)

29.2.26 Controlling and Monitoring the ePWM Dead-Band Submodule

The dead-band generator submodule operation is controlled and monitored via the following registers:

Table 29-38 Dead-Band Generator Submodule Registers
AcronymRegister DescriptionAddress OffsetShadowed
EPWM_DBCTLDead-Band Control Register1EhNo
EPWM_DBREDDead-Band Rising Edge Delay Count Register20hNo
EPWM_DBFEDDead-Band Falling Edge Delay Count Register22hNo

29.2.27 Operational Highlights for the ePWM Dead-Band Generator Submodule

The following sections provide the operational highlights.

The dead-band submodule has two groups of independent selection options as shown in Figure 29-33.

  • Input Source Selection: The input signals to the dead-band module are the EPWMxA and EPWMxB output signals from the action-qualifier. In this section they will be referred to as EPWMxA In and EPWMxB In. Using the EPWM_DBCTL[5:4] IN_MODE control bits, the signal source for each delay, falling-edge or rising-edge, can be selected:
    • EPWMxA In is the source for both falling-edge and rising-edge delay. This is the default mode.
    • EPWMxA In is the source for falling-edge delay, EPWMxB In is the source for rising-edge delay.
    • EPWMxA In is the source for rising edge delay, EPWMxB In is the source for falling-edge delay.
    • EPWMxB In is the source for both falling-edge and rising-edge delay.
  • Output Mode Control: The output mode is configured by way of the EPWM_DBCTL[1:0] OUT_MODE bits. These bits determine if the falling-edge delay, rising-edge delay, neither, or both are applied to the input signals.
  • Polarity Control: The polarity control (EPWM_DBCTL[3:2] POLSEL) allows you to specify whether the rising-edge delayed signal and/or the falling-edge delayed signal is to be inverted before being sent out of the dead-band submodule.

AM571x Configuration Options for the ePWM Dead-Band Generator SubmoduleFigure 29-33 Configuration Options for the ePWM Dead-Band Generator Submodule

Although all combinations are supported, not all are typical usage modes. Table 29-39 lists some classical dead-band configurations. These modes assume that the EPWM_DBCTL[5:4] IN_MODE is configured such that EPWMxA In is the source for both falling-edge and rising-edge delay. Enhanced, or non-traditional modes can be achieved by changing the input signal source. The modes shown in Table 29-39 fall into the following categories:

  • Mode 1: Bypass both falling-edge delay (FED) and rising-edge delay (RED) Allows you to fully disable the dead-band submodule from the PWM signal path.
  • Mode 2-5: Classical Dead-Band Polarity Settings These represent typical polarity configurations that should address all the active high/low modes required by available industry power switch gate drivers. The waveforms for these typical cases are shown in Figure 29-34. Note that to generate equivalent waveforms to Figure 29-34, configure the action-qualifier submodule to generate the signal as shown for EPWMxA.
  • Mode 6: Bypass rising-edge-delay and Mode 7: Bypass falling-edge-delay Finally the last two entries in Table 29-39 show combinations where either the falling-edge-delay (FED) or rising-edge-delay (RED) blocks are bypassed.

5Active Low (AL)1111
6EPWMxA Out = EPWMxA In (No Delay)0 or 10 or 101
EPWMxB Out = EPWMxA In with Falling Edge Delay
7EPWMxA Out = EPWMxA In with Rising Edge Delay0 or 10 or 110
EPWMxB Out = EPWMxB In with No Delay
(1) These are classical dead-band modes and assume that EPWM_DBCTL[5:4] IN_MODE = 0b00. That is, EPWMxA in is the source for both the falling-edge and rising-edge delays. Enhanced, non-traditional modes can be achieved by changing the IN_MODE configuration.

Figure 29-34 shows waveforms for typical cases where 0% < duty < 100%.

AM571x Dead-Band Waveforms for Typical Cases (0% < Duty < 100%)Figure 29-34 Dead-Band Waveforms for Typical Cases (0% < Duty < 100%)

The dead-band submodule supports independent values for rising-edge (RED) and falling-edge (FED) delays. The amount of delay is programmed using the EPWM_DBRED and EPWM_DBFED registers. These are 10-bit registers and their value represents the number of time-base clock, TBCLK, periods a signal edge is delayed by. For example, the formula to calculate falling-edge-delay and rising-edge-delay are:

FED = EPWM_DBFED × TTBCLK

RED = EPWM_DBRED × TTBCLK

Where TTBCLK is the period of TBCLK, the prescaled version of SYSCLKOUT.

29.2.28 PWM-Chopper (PC) Submodule

Figure 29-35 illustrates the PWM-chopper (PC) submodule within the ePWM module. The PWM-chopper submodule allows a high-frequency carrier signal to modulate the PWM waveform generated by the action-qualifier and dead-band submodules. This capability is important if you need pulse transformer-based gate drivers to control the power switching elements.

AM571x PWM-Chopper SubmoduleFigure 29-35 PWM-Chopper Submodule

29.2.29 Purpose of the PWM-Chopper Submodule

The key functions of the PWM-chopper submodule are:

  • Programmable chopping (carrier) frequency
  • Programmable pulse width of first pulse
  • Programmable duty cycle of second and subsequent pulses
  • Can be fully bypassed if not required

29.2.30 Controlling the PWM-Chopper Submodule

The PWM-chopper submodule operation is controlled via the register in Table 29-40.

29.2.31 Operational Highlights for the PWM-Chopper Submodule

Figure 29-36 shows the operational details of the PWM-chopper submodule. The carrier clock is derived from SYSCLKOUT. Its frequency and duty cycle are controlled via the CHPFREQ and CHPDUTY bits in the EPWM_PCCTL register. The one-shot block is a feature that provides a high energy first pulse to ensure hard and fast power switch turn on, while the subsequent pulses sustain pulses, ensuring the power switch remains on. The one-shot width is programmed via the OSHTWTH bits. The PWM-chopper submodule can be fully disabled (bypassed) via the CHPEN bit.

AM571x PWM-Chopper Submodule Signals and RegistersFigure 29-36 PWM-Chopper Submodule Signals and Registers

29.2.32 PWM Chopper Waveforms

Figure 29-37 shows simplified waveforms of the chopping action only; one-shot and duty-cycle control are not shown. Details of the one-shot and duty-cycle control are discussed in the following sections.

AM571x Simple PWM-Chopper Submodule Waveforms Showing Chopping Action OnlyFigure 29-37 Simple PWM-Chopper Submodule Waveforms Showing Chopping Action Only

29.2.33 PWM-Chopper One-Shot Pulse

The width of the first pulse can be programmed to any of 16 possible pulse width values. The width or period of the first pulse is given by:

T1stpulse = TSYSCLKOUT × 8 × OSHTWTH

Where TSYSCLKOUT is the period of the system clock (SYSCLKOUT) and OSHTWTH is the four control bits (value from 1 to 16)

Figure 29-38 shows the first and subsequent sustaining pulses.

AM571x PWM-Chopper Submodule Waveforms Showing the First Pulse and Subsequent Sustaining PulsesFigure 29-38 PWM-Chopper Submodule Waveforms Showing the First Pulse and
Subsequent Sustaining Pulses

29.2.34 PWM-Chopper Duty Cycle Control

Pulse transformer-based gate drive designs need to comprehend the magnetic properties or characteristics of the transformer and associated circuitry. Saturation is one such consideration. To assist the gate drive designer, the duty cycles of the second and subsequent pulses have been made programmable. These sustaining pulses ensure the correct drive strength and polarity is maintained on the power switch gate during the on period, and hence a programmable duty cycle allows a design to be tuned or optimized via software control.

Figure 29-39 shows the duty cycle control that is possible by programming the CHPDUTY bits. One of seven possible duty ratios can be selected ranging from 12.5% to 87.5%.

29.2.35 ePWM Trip-Zone (TZ) Submodule

Figure 29-40 shows how the trip-zone (TZ) submodule fits within the ePWM module. Each ePWM module is connected to every TZ signal that are sourced from the GPIO MUX. These signals indicates external fault or trip conditions, and the ePWM outputs can be programmed to respond accordingly when faults occur. See Section 29.1.3 to determine the number of trip-zone pins available for the device.

AM571x ePWM Trip-Zone SubmoduleFigure 29-40 ePWM Trip-Zone Submodule

29.2.36 Purpose of the ePWM Trip-Zone Submodule

The key functions of the trip-zone submodule are:

  • Trip inputs TZ0 to TZk-1 can be flexibly mapped to any ePWM module.
  • Upon a fault condition, outputs EPWMxA and EPWMxB can be forced to one of the following:
    • High
    • Low
    • High-impedance
    • No action taken
  • Support for one-shot trip (OSHT) for major short circuits or over-current conditions.
  • Support for cycle-by-cycle tripping (CBC) for current limiting operation.
  • Each trip-zone input pin can be allocated to either one-shot or cycle-by-cycle operation.
  • Interrupt generation is possible on any trip-zone pin.
  • Software-forced tripping is also supported.
  • The trip-zone submodule can be fully bypassed if it is not required.
Note:

For each ePWMx, from the tripzone inputs EPWM_TRIP_TZ[5:0], ONLY the EPWM_TRIP_TZ[0] input of ePWM tripzone is chip accessible and usable, i.e. k=1.

29.2.37 Controlling and Monitoring the ePWM Trip-Zone Submodule

The trip-zone submodule operation is controlled and monitored through the following registers:

29.2.38 Operational Highlights for the ePWM Trip-Zone Submodule

The following sections describe the operational highlights and configuration options for the trip-zone submodule.

The trip-zone signals at pin TZ0 to TZk-1 is an active-low input signal. When the pin goes low, it indicates that a trip event has occurred. Each ePWM module can be individually configured to ignore or use each of the trip-zone pins. Which trip-zone pins are used by a particular ePWM module is determined by the EPWM_TZSEL register for that specific ePWM module. The trip-zone signal may or may not be synchronized to the system clock (SYSCLKOUT). A minimum of 1 SYSCLKOUT low pulse on the TZn inputs is sufficient to trigger a fault condition in the ePWM module. The asynchronous trip makes sure that if clocks are missing for any reason, the outputs can still be tripped by a valid event present on the TZk inputs.

Note:

Only the TZ[0] input is accessible at chip level (i.e. k=1).

The TZk input can be individually configured to provide either a cycle-by-cycle or one-shot trip event for a ePWM module. The configuration is determined by the EPWM_TZSEL[7:0] CBCk and EPWM_TZSEL[15:8] OSHTk bits (where k corresponds to the trip pin) respectively.

  • Cycle-by-Cycle (CBC): When a cycle-by-cycle trip event occurs, the action specified in the EPWM_TZCTL register is carried out immediately on the EPWMxA and/or EPWMxB output. Table 29-42 lists the possible actions. In addition, the cycle-by-cycle trip event flag (EPWM_TZFLG[1] CBC) is set and a EPWMxTZINT interrupt is generated if it is enabled in the EPWM_TZEINT register.

    The specified condition on the pins is automatically cleared when the ePWM time-base counter reaches zero (EPWM_TBCNT bitfield TBCNT = 0000h) if the trip event is no longer present. Therefore, in this mode, the trip event is cleared or reset every PWM cycle. The EPWM_TZFLG[1] CBC flag bit will remain set until it is manually cleared by writing to the EPWM_TZCLR[1] CBC bit. If the cycle-by-cycle trip event is still present when the EPWM_TZFLG[1] CBC bit is cleared, then it will again be immediately set.

  • One-Shot (OSHT): When a one-shot trip event occurs, the action specified in the EPWM_TZCTL register is carried out immediately on the EPWMxA and/or EPWMxB output. Table 29-42 lists the possible actions. In addition, the one-shot trip event flag (EPWM_TZFLG[2] OST) is set and a EPWMxTZINT interrupt is generated if it is enabled in the EPWM_TZEINT register. The one-shot trip condition must be cleared manually by writing to the EPWM_TZCLR[2] OST bit.

The action taken when a trip event occurs can be configured individually for each of the ePWM output pins by way of the EPWM_TZCTL[1:0] TZA and EPWM_TZCTL[3:2] TZB register bits. One of four possible actions, shown in Table 29-42, can be taken on a trip event.

29.2.39 ePWM Trip-Zone Configurations

Scenario A:
A one-shot trip event on TZ0 pulls both EPWM1A, EPWM1B low and also forces EPWM2A and EPWM2B high.

  • Configure the ePWM1 registers as follows:
    • EPWM_TZSEL[8] OSHT1 = 1: enables TZ as a one-shot event source for ePWM1
    • EPWM_TZCTL[1:0] TZA = 2: EPWM1A will be forced low on a trip event.
    • EPWM_TZCTL[3:2] TZB = 2: EPWM1B will be forced low on a trip event.
  • Configure the ePWM2 registers as follows:
    • EPWM_TZSEL[8] OSHT1 = 1: enables TZ as a one-shot event source for ePWM2
    • EPWM_TZCTL[1:0] TZA = 1: EPWM2A will be forced high on a trip event.
    • EPWM_TZCTL[3:2] TZB = 1: EPWM2B will be forced high on a trip event.

29.2.41 ePWM Event-Trigger (ET) Submodule

Figure 29-43 shows the event-trigger (ET) submodule in the ePWM system. The event-trigger submodule manages the events generated by the time-base submodule and the counter-compare submodule to generate an aggregated interrupt request.

Note:

The ePWMx ET interrupt request output is further routed via the device IRQ_CROSSBAR, to different device host interrupt controllers, located outside PWMSSn. For more details on interrupt event routing outside the ePWM, refer to the Section 29.1.3.

AM571x ePWM Event-Trigger SubmoduleFigure 29-43 ePWM Event-Trigger Submodule

29.2.42 Purpose of the ePWM Event-Trigger Submodule

The key functions of the event-trigger submodule are:

  • Receives event inputs generated by the time-base and counter-compare submodules
  • Uses the time-base direction information for up/down event qualification
  • Uses prescaling logic to issue interrupt requests at:
    • Every event
    • Every second event
    • Every third event
  • Provides full visibility of event generation via event counters and flags

29.2.43 Controlling and Monitoring the ePWM Event-Trigger Submodule

The key registers used to configure the event-trigger submodule are shown in Table 29-43:

29.2.44 Operational Overview of the ePWM Event-Trigger Submodule

The following sections describe the event-trigger submodule's operational highlights.

Each ePWM module has one interrupt request line as shown in Figure 29-44. Mapping interrupt lines to device host interrupt controllers is device specific and is covered in the Section 29.1.3.

AM571x ePWM Event-Trigger Submodule Inter-Connectivity to Interrupt ControllerFigure 29-44 ePWM Event-Trigger Submodule Inter-Connectivity to Interrupt Controller

The event-trigger submodule monitors various event conditions (the left side inputs to event-trigger submodule shown in Figure 29-45) and can be configured to prescale these events before issuing an Interrupt request. The event-trigger prescaling logic can issue Interrupt requests at:

  • Every event
  • Every second event
  • Every third event
AM571x ePWM Event-Trigger Submodule Showing Event Inputs and Prescaled OutputsFigure 29-45 ePWM Event-Trigger Submodule Showing Event Inputs and Prescaled Outputs

  • ETSEL—This selects which of the possible events will trigger an interrupt.
  • ETPS—This programs the event prescaling options previously mentioned.
  • ETFLG—These are flag bits indicating status of the selected and prescaled events.
  • ETCLR—These bits allow you to clear the flag bits in the EPWM_ETFLG register via software.
  • ETFRC—These bits allow software forcing of an event. Useful for debugging or software intervention.

A more detailed look at how the various register bits interact with the Interrupt is shown in Figure 29-46.

Figure 29-46 shows the event-trigger's interrupt generation logic. The interrupt-period (EPWM_ETPS[1:0] INTPRD) bits specify the number of events required to cause an interrupt pulse to be generated. The choices available are:

  • Do not generate an interrupt
  • Generate an interrupt on every event
  • Generate an interrupt on every second event
  • Generate an interrupt on every third event

An interrupt cannot be generated on every fourth or more events.

Which event can cause an interrupt is configured by the interrupt selection (EPWM_ETSEL[2:0] INTSEL) bits. The event can be one of the following:

  • Time-base counter equal to zero (EPWM_TBCNT bitfield TBCNT = 0000h).
  • Time-base counter equal to period (EPWM_TBCNT bitfield TBCNT = TBPRD value in EPWM_TBPRD active register).
  • Time-base counter equal to the compare A register (EPWM_CMPA) when the timer is incrementing.
  • Time-base counter equal to the compare A register (EPWM_CMPA) when the timer is decrementing.
  • Time-base counter equal to the compare B register (EPWM_CMPB) when the timer is incrementing.
  • Time-base counter equal to the compare B register (EPWM_CMPB) when the timer is decrementing.

The number of events that have occurred can be read from the interrupt event counter (EPWM_ETPS[3:2] INTCNT) register bits. That is, when the specified event occurs the EPWM_ETPS[3:2] INTCNT bits are incremented until they reach the value specified by EPWM_ETPS[1:0] INTPRD. When EPWM_ETPS[3:2] INTCNT = EPWM_ETPS[1:0] INTPRD the counter stops counting and its output is set. The counter is only cleared when an interrupt is sent to the interrupt controller.

When EPWM_ETPS[3:2] INTCNT reaches EPWM_ETPS[1:0] INTPRD, one of the following behaviors will occur:

  • If interrupts are enabled, EPWM_ETSEL[3] INTEN = 1 and the interrupt flag is clear, EPWM_ETFLG[0] INT = 0, then an interrupt pulse is generated and the interrupt flag is set, EPWM_ETFLG[0] INT = 1, and the event counter is cleared EPWM_ETPS[3:2] INTCNT = 0. The counter will begin counting events again.
  • If interrupts are disabled, EPWM_ETSEL[3] INTEN = 0, or the interrupt flag is set, EPWM_ETFLG[0] INT = 1, the counter stops counting events when it reaches the period value EPWM_ETPS[3:2] INTCNT = EPWM_ETPS[1:0] INTPRD.
  • If interrupts are enabled, but the interrupt flag is already set, then the counter will hold its output high until the ENTFLG[0] INT flag is cleared. This allows for one interrupt to be pending while one is serviced.

Writing to the INTPRD bits will automatically clear the counter INTCNT = 0 and the counter output will be reset (so no interrupts are generated). Writing a 1 to the EPWM_ETFRC[0] INT bit will increment the event counter INTCNT. The counter will behave as described above when INTCNT = INTPRD. When INTPRD = 0, the counter is disabled and hence no events will be detected and the EPWM_ETFRC[0] INT bit is also ignored.

29.2.45 High-Resolution PWM (HRPWM) Submodule

Figure 29-47 shows the high-resolution PWM (HRPWM) submodule in the ePWM system. Some devices include the high-resolution PWM submodule, see Section 29.1.3 to determine which ePWM instances include this feature.

AM571x HRPWM System InterfaceFigure 29-47 HRPWM System Interface

29.2.46 Purpose of the High-Resolution PWM Submodule

The enhanced high-resolution pulse-width modulator (eHRPWM) extends the time resolution capabilities of the conventionally derived digital pulse-width modulator (PWM). HRPWM is typically used when PWM resolution falls below ~9-10 bits. The key features of HRPWM are:

  • Extended time resolution capability
  • Used in both duty cycle and phase-shift control methods
  • Finer time granularity control or edge positioning using extensions to the Compare A and Phase registers
  • Implemented using the A signal path of PWM, that is, on the EPWMxA output. EPWMxB output has conventional PWM capabilities

The ePWM peripheral is used to perform a function that is mathematically equivalent to a digital-to-analog converter (DAC). As shown in Figure 29-48, the effective resolution for conventionally generated PWM is a function of PWM frequency (or period) and system clock frequency.

If the required PWM operating frequency does not offer sufficient resolution in PWM mode, you may want to consider HRPWM. As an example of improved performance offered by HRPWM, Table 29-44 shows resolution in bits for various PWM frequencies. Table 29-44 values assume a MEP step size of 180 ps. See your device-specific data manual for typical and maximum performance specifications for the MEP.

Although each application may differ, typical low-frequency PWM operation (below 250 kHz) may not require HRPWM. HRPWM capability is most useful for high-frequency PWM requirements of power conversion topologies such as:

  • Single-phase buck, boost, and flyback
  • Multi-phase buck, boost, and flyback
  • Phase-shifted full bridge
  • Direct modulation of D-Class power amplifiers

29.2.47 Architecture of the High-Resolution PWM Submodule

The HRPWM is based on micro edge positioner (MEP) technology. MEP logic is capable of positioning an edge very finely by sub-dividing one coarse system clock of a conventional PWM generator. The time step accuracy is on the order of 150 ps. The HRPWM also has a self-check software diagnostics mode to check if the MEP logic is running optimally, under all operating conditions.

Figure 29-49 shows the relationship between one coarse system clock and edge position in terms of MEP steps, which are controlled via an 8-bit field in the Compare A extension register (HRPWM_CMPAHR).

Figure 29-49 Operating Logic Using MEP

To generate an HRPWM waveform, configure the TBM, CCM, and AQM registers as you would to generate a conventional PWM of a given frequency and polarity. The HRPWM works together with the TBM, CCM, and AQM registers to extend edge resolution, and should be configured accordingly. Although many programming combinations are possible, only a few are needed and practical.

29.2.48 Controlling and Monitoring the High-Resolution PWM Submodule

The MEP of the HRPWM is controlled by two extension registers, each 8-bits wide. These two HRPWM registers are concatenated with the 16-bit EPWM_TBPHS and EPWM_CMPA registers used to control PWM operation.

Table 29-45 lists the registers used to control and monitor the high-resolution PWM submodule.

HRPWM_HRCTLHRPWM Configuration Register1040hNo

29.2.49 Configuring the High-Resolution PWM Submodule

Once the ePWM has been configured to provide conventional PWM of a given frequency and polarity, the HRPWM is configured by programming the HRPWM_HRCTL register located at offset address 1040h. This register provides configuration options for the following key operating modes:

  • Edge Mode: The MEP can be programmed to provide precise position control on the rising edge (RE), falling edge (FE), or both edges (BE) at the same time. FE and RE are used for power topologies requiring duty cycle control, while BE is used for topologies requiring phase shifting, for example, phase shifted full bridge.
  • Control Mode: The MEP is programmed to be controlled either from the HRPWM_CMPAHR register (duty cycle control) or the HRPWM_TBPHSHR register (phase control). RE or FE control mode should be used with HRPWM_CMPAHR register. BE control mode should be used with HRPWM_TBPHSHR register.
  • Shadow Mode: This mode provides the same shadowing (double buffering) option as in regular PWM mode. This option is valid only when operating from the HRPWM_CMPAHR register and should be chosen to be the same as the regular load option for the CMPA register. If HRPWM_TBPHSHR is used, then this option has no effect.

29.2.50 Operational Highlights for the High-Resolution PWM Submodule

The MEP logic is capable of placing an edge in one of 255 (8 bits) discrete time steps, each of which has a time resolution on the order of 150 ps. The MEP works with the TBM and CCM registers to be certain that time steps are optimally applied and that edge placement accuracy is maintained over a wide range of PWM frequencies, system clock frequencies and other operating conditions. Table 29-46 shows the typical range of operating frequencies supported by the HRPWM.

29.2.51 HRPWM Edge Positioning

In a typical power control loop (switch modes, digital motor control (DMC), uninterruptible power supply (UPS)), a digital controller (PID, 2pole/2zero, lag/lead, etc.) issues a duty command, usually expressed in a per unit or percentage terms.

In the following example, assume that for a particular operating point, the demanded duty cycle is 0.405 or 40.5% on-time and the required converter PWM frequency is 1.25 MHz. In conventional PWM generation with a system clock of 100 MHz, the duty cycle choices are in the vicinity of 40.5%. In Figure 29-50, a compare value of 32 counts (duty = 40%) is the closest to 40.5% that you can attain. This is equivalent to an edge position of 320 ns instead of the desired 324 ns. This data is shown in Table 29-47.

By utilizing the MEP, you can achieve an edge position much closer to the desired point of 324 ns. Table 29-47 shows that in addition to the CMPA value, 22 steps of the MEP (HRPWM_CMPAHR register) will position the edge at 323.96 ns, resulting in almost zero error. In this example, it is assumed that the MEP has a step resolution of 180 ns.

29.2.52 HRPWM Scaling Considerations

The mechanics of how to position an edge precisely in time has been demonstrated using the resources of the standard (EPWM_CMPA) and MEP (HRPWM_CMPAHR) registers. In a practical application, however, it is necessary to seamlessly provide the CPU a mapping function from a per-unit (fractional) duty cycle to a final integer (non-fractional) representation that is written to the [CMPA:CMPAHR] register combination.

To do this, first examine the scaling or mapping steps involved. It is common in control software to express duty cycle in a per-unit or percentage basis. This has the advantage of performing all needed math calculations without concern for the final absolute duty cycle, expressed in clock counts or high time in ns. Furthermore, it makes the code more transportable across multiple converter types running different PWM frequencies.

To implement the mapping scheme, a two-step scaling procedure is required.

Assumptions for this example:

System clock, SYSCLKOUT=10 ns (100 MHz)
PWM frequency=1.25 MHz (1/800 ns)
Required PWM duty cycle, PWMDuty=0.405 (40.5%)
PWM period in terms of coarse steps,

Step 1: Percentage Integer Duty value conversion for EPWM_CMPA register

EPWM_CMPA register value=int(PWMDuty × PWMperiod); int means integer part
=int(0.405 × 80)
=int(32.4)
EPWM_CMPA register value=32 (20h)

Step 2: Fractional value conversion for HRPWM_CMPAHR register

HRPWM_CMPAHR register value=(frac(PWMDuty × PWMperiod) × MEP_SF) << 8) + 180h; frac means fractional part
=(frac(32.4) × 55 <<8) + 180h; Shift is to move the value as CMPAHR high byte
=((0.4 × 55) <<8) + 180h
=(22 <<8) + 180h
=22 × 256 + 180h ; Shifting left by 8 is the same multiplying by 256.
=5632 + 180h
=1600h + 180h
HRPWM_CMPAHR value=1780h; HRPWM_CMPAHR value = 1700h, lower 8 bits will be ignored by hardware.

29.2.53 HRPWM Duty Cycle Range Limitation

In high resolution mode, the MEP is not active for 100% of the PWM period. It becomes operational 3 SYSCLKOUT cycles after the period starts.

Duty cycle range limitations are illustrated in Figure 29-51. This limitation imposes a lower duty cycle limit on the MEP. For example, precision edge control is not available all the way down to 0% duty cycle. Although for the first 3 or 6 cycles, the HRPWM capabilities are not available, regular PWM duty control is still fully operational down to 0% duty. In most applications this should not be an issue as the controller regulation point is usually not designed to be close to 0% duty cycle.

AM571x Low % Duty Cycle Range Limitation Example When PWM Frequency = 1 MHzFigure 29-51 Low % Duty Cycle Range Limitation Example When PWM Frequency = 1 MHz

If the application demands HRPWM operation in the low percent duty cycle region, then the HRPWM can be configured to operate in count-down mode with the rising edge position (REP) controlled by the MEP. This is illustrated in Figure 29-52. In this case low percent duty limitation is no longer an issue.
