16.4.1.2 Comparator Outputs

The comparator output can be used to trigger PWM modules or interrupts for actions based on the comparator event. When the digital filter is disabled, the comparator signal is made directly available to the PWM module as a current limit and/or Fault signal. This ensures minimal latency for Current-mode applications and for time-critical (safety) applications. The status signal and the interrupt request signal will be processed by the pulse stretcher circuit. When the digital filter is enabled, the PWM trigger signal, status signal and interrupt request signal are all processed by the pulse stretcher and the digital filter logic. This will cause a delay in the current limit/Fault limit event. The polarity of the comparator output is selected by configuring the CMPPOL bit (DACxCON[6]). The comparator output can be monitored on the I/O pin by configuring the Peripheral Pin Select (PPS) register.
