operation is being executed (start of the
Q2 cycle), then the CxIF of the PIR1
register interrupt flag may not get set.
bias circuitry in the Comparator module
may cause an invalid output from the
comparator until the bias circuitry is stable.
Allow about 1 s for bias settling then clear
the mismatch condition and interrupt flags
before enabling comparator interrupts.
