6 Device Configurations

6.1 Control Module

The device control module includes status and control logic not addressed within the peripherals or the remainder of the device infrastructure. This module is the primary point of control for the following areas of the device:

  • Functional IO multiplexing
  • Device status
  • Static device configuration
  • Open-core protocol (OCP) interface for standard and customer programmable e-Fuse bit shift registers.

The control module primarily implements a bank of registers accessible (read and write) by the software along with some read-only registers carrying status information. Most register bits are exported as control signals for other logic blocks on the device. Certain control module registers have default values based upon the device type as decoded from e-Fuse.

The read and write registers can be divided into the following classes:

  • Static device configuration registers
  • Status and configuration registers
  • Boot registers

Table 6-1 shows the general register groupings and Table 6-2 through Table 6-4 provide register summaries for each group.

6.2 Revision Identification

The silicon revision can be read in the DEVREV bit field value of the device identification (DEVICE_ID) register (located at 0x4814 0600). The DEVREV field of the DEVICE_ID register changes between silicon revisions. Table 6-5 lists the contents of the device revision (DEVREV) field value for each revision of the device.

6.3 Debugging Considerations

6.3.1 Pullup and Pulldown Resistors

Proper board design should ensure that input pins to the device always be at a valid logic level and not floating. This may be achieved via pullup and pulldown resistors. The device features internal pullup (IPU) and internal pulldown (IPD) resistors on most pins to eliminate the need, unless otherwise noted, for external pullup or pulldown resistors.

An external pullup or pulldown resistor needs to be used in the following situations:

  • Boot and Configuration Pins: If the pin is both routed out and 3-stated (not driven), an external pullup or pulldown resistor is strongly recommended, even if the IPU or IPD matches the desired value or state.
  • Other Input Pins: If the IPU or IPD does not match the desired value or state, use an external pullup or pulldown resistor to pull the signal to the opposite rail.

For the boot and configuration pins (listed in Table 4-1, Boot Terminal Functions), if they are both routed out and 3-stated (not driven), it is strongly recommended that an external pullup or pulldown resistor be implemented. Although, internal pullup and pulldown resistors exist on these pins and they may match the desired configuration value, providing external connectivity can help ensure that valid logic levels are latched on these device boot and configuration pins. In addition, applying external pullup or pulldown resistors on the boot and configuration pins adds convenience to the user in debugging and flexibility in switching operating modes.

Tips for choosing an external pullup or pulldown resistor:

  • Consider the total amount of current that may pass through the pullup or pulldown resistor. Make sure to include the leakage currents of all the devices connected to the net, as well as any internal pullup or pulldown resistors.
  • Decide a target value for the net. For a pulldown resistor, this should be below the lowest VIL level of all inputs connected to the net. For a pullup resistor, this should be above the highest VIH level of all inputs on the net. A reasonable choice would be to target the VOL or VOH levels for the logic family of the limiting device; which, by definition, have margin to the VIL and VIH levels.
  • Select a pullup or pulldown resistor with the largest possible value; but, which can still ensure that the net will reach the target pulled value when maximum current from all devices on the net is flowing through the resistor. The current to be considered includes leakage current plus, any other internal and external pullup and pulldown resistors on the net.
  • For bidirectional nets, there is an additional consideration which sets a lower limit on the resistance value of the external resistor. Verify that the resistance is small enough that the weakest output buffer can drive the net to the opposite logic level (including margin).
  • Remember to include tolerances when selecting the resistor value.
  • For pullup resistors, also remember to include tolerances on the DVDD rail.

For most systems, a 1-kΩ resistor can be used to oppose the IPU or IPD while meeting the above criteria. Users should confirm this resistor value is correct for their specific application.

For most systems, a 20-kΩ resistor can be used to compliment the IPU or IPD on the boot and configuration pins while meeting the above criteria. Users should confirm this resistor value is correct for their specific application.

For most systems, a 20-kΩ resistor can also be used as an external pullup or pulldown on the pins that have IPUs or IPDs disabled and require an external pullup or pulldown resistor while still meeting the above criteria. Users should confirm this resistor value is correct for their specific application.

For more detailed information on input current (II), and the low-level or high-level input voltages (VIL and VIH), see , Electrical Characteristics Over Recommended Ranges of Supply Voltage and Operating Temperature.

For the internal pullup and pulldown resistors for all device pins, see the peripheral-specific or system-specific terminal functions tables in Section 4.2.

6.4 Boot Sequence

The boot sequence is a process by which the device's memory is loaded with program and data sections, and by which some of the device's internal registers are programmed with predetermined values. The boot sequence is started automatically after each device-level global reset. For more details on device-level global resets, see Section 8.2. There are several methods by which the memory and register initialization can take place. Each of these methods is referred to as a boot mode. The boot mode to be used is selected at reset. The device is booted through multiple means—primary bootloaders within internal ROM or EMIF4, and secondary user bootloaders from peripherals or external memories. The maximum size of the boot image is 255KB (ROM uses 1KB internally). Boot modes, pin configurations, and register configurations required for booting the device, are described in the following subsections.

The following boot modes are supported:

  • NOR Flash boot (muxed and non-muxed, 8-bit or 16-bit)
  • NAND Flash boot (SLC and MLC with BCH ECC, 8-bit or 16-bit)
  • SPI boot (EEPROM or Flash, SPI mode 3, 24-bit)
  • SD boot (SD cards)
  • EMAC boot (TFTP client)
  • UART boot (X-modem client)
  • PCIe boot (client mode, PCIe 32 and PCIe 64).

The state of the device after boot is determined by sampling the input states of the BTMODE[4:0] pins when device reset (POR or RESET) is deasserted. The sampled values are latched into the CONTROL_STATUS register, which is part of the system configuration (SYSCFG) module.

The BTMODE [4:0] values determine the boot mode order according to Table 6-6. The first boot mode listed for each BTMODE[4:0] configuration is executed as the primary boot mode. If the primary boot mode fails, the second, third, and fourth boot modes are executed, in that order, until a successful boot is completed.

Additional boot configuration pins determine the following system boot settings as shown in Table 4-1:

  • GPMC CS0 Default Bus Width
  • GPMC Wait Enable
  • GPMC Address and Data Multiplexing.

The GPMC CS0 default operation is determined by the CS0BW, CS0WAIT, and CS0MUX[1:0] inputs.

For more detailed information on booting the device, see the AM389x Sitara ARM Processors Technical Reference Manual (literature number SPRUGX7).

6.5 Pin Multiplexing Control

Device-level pin multiplexing is controlled on a pin-by-pin basis by the MUXMODE bits of the PINCTRL1 - PINCTRL321 registers in the SYSCFG module. The default state for each multiplexed pin is MUXMODE = 0x000.

Pin multiplexing selects which of several peripheral pin functions control the pin's IO buffer output data values.

The input from each pin is routed to all of the peripherals that share the pin, regardless of the MUXMODE setting. For details, see the table below and the MUXED column in the each of the Terminal Functions tables in Section 4.2.

6.6 How to Handle Unused Pins

When device signal pins are unused in the system, they can be left unconnected unless otherwise instructed in the Terminal Functions tables. For unused input pins, the internal pull resistor should be enabled, or an external pull resistor should be used, to prevent floating inputs. All supply pins must always be connected to the correct voltage, even when their associated signal pins are unused, as instructed in the Terminal Functions tables in Section 4.2.
