REGISTER 6-2:
6.9
The comparator interrupt flag is set whenever there is
a change in the output value of the comparator.
Software will need to maintain information about the
status of the output bits, as read from CMCON<6>, to
determine the actual change that has occurred. The
CMIF bit, PIR1<3>, is the comparator interrupt flag.
This bit must be reset in software by clearing it to ‘0’.
Since it is also possible to write a ‘1’ to this register, a
simulated interrupt may be initiated.
The CMIE bit (PIE1<3>) and the PEIE bit (INT-
CON<6>) must be set to enable the interrupt. In addi-
tion, the GIE bit must also be set. If any of these bits are
cleared, the interrupt is not enabled, though the CMIF
bit will still be set if an interrupt condition occurs.

The user, in the Interrupt Service Routine, can clear the
interrupt in the following manner:
a)
b)
A mismatch condition will continue to set flag bit CMIF.
Reading CMCON will end the mismatch condition, and
allow flag bit CMIF to be cleared.

If a change in the CMCON register (COUT)
should occur when a read operation is
being executed (start of the Q2 cycle), then
the CMIF (PIR1<3>) interrupt flag may not
get set.
