by a comparator output or INT pin event,
a software shutdown can be triggered in
firmware by setting the CCPxASE bit to a
‘1’. The Auto-Restart feature tracks the
active status of a shutdown caused by a
comparator output or INT pin event only,
so if it is enabled at this time, it will imme-
diately clear this bit and restart the ECCP
module at the beginning of the next PWM
period.
