Brown-out Reset
Comparator
An internal Brown-out Reset (BOR) circuit was added as a special feature. This circuit will be
added to most new devices. The exception will be for devices whose target market will require
normal operation below the BOR trip point (handheld battery applications).
devices that evolved into having the BOR circuitry.
Table C-3:
If a change in the CMCON register (C1OUT or C2OUT) should occur when a read operation is
being executed (start of the Q2 cycle), then the CMIF interrupt flag bit may not get set.
