For proper operation of the digital filter, the following initialization sequence is recommended:
- Configure and enable the comparator for operation.
- Configure the digital filter parameters for operation:
- Set SAMPWIN for the number of samples to monitor in the FIFO window.
- Set THRESH for the threshold required for majority qualification.
- Set CLKPRESCALE for the digital filter clock prescale value.
- Initialize the sample values in the digital FIFO window by setting FILINIT.
- Clear COMPSTS latch using COMPSTSCLR, if the latched path is desired.
- Configure the CTRIP and CTRIPOUT signal paths.
- If desired, configure the destination module, for example, ePWM, GPIO, and so on to accept the filtered signals.
