8.1.20 Control Peripherals

The devices support the following peripherals that are used for embedded control and communication:

ePWM: The ePWM peripheral supports independent/complementary PWM generation, adjustable dead-band generation for leading/trailing edges, latched/cycle-by-cycle trip mechanism. The type 1 module found on 2805x devices also supports increased dead-band resolution, enhanced SOC and interrupt generation, and advanced triggering including trip functions based on comparator outputs.
eCAP: The eCAP peripheral uses a 32-bit time base and registers up to four programmable events in continuous/one-shot capture modes.
This peripheral can also be configured to generate an auxiliary PWM signal.
eQEP: The eQEP peripheral uses a 32-bit position counter, supports low-speed measurement using capture unit and high-speed measurement using a 32-bit unit timer. This peripheral has a watchdog timer to detect motor stall and input error detection logic to identify simultaneous edge transition in QEP signals.
ADC: The ADC block is a 12-bit converter. The ADC has up to 16 single-ended channels pinned out, depending on the device. The ADC also contains two sample-and-hold units for simultaneous sampling. Some ADC channels also have PGAs, which can amplify the input signal by 3, 6, or 11.
Comparator and
Digital Filter Subsystems:		 Each comparator block consists of one analog comparator along with an internal 6-bit reference for supplying one input of the comparator. The comparator output signal filtering is achieved using the digital filter present on each input line and qualifies the output of the COMP/DAC subsystem. The filtered or unfiltered output of the COMP/DAC subsystem can be configured to be an input to the Digital Compare submodule of the ePWM peripheral. There is also a configurable option to bring the output of the COMP/DAC subsystem onto the GPIOs.
