The
comparators. The inputs to the comparators are
multiplexed with pins RA0 through RA4. The on-chip
Voltage Reference (Section 8.0) can also be an input to
the comparators.

C2OUT : Comparator 2 output
1 = C2 V
0 = C2 V
C1OUT : Comparator 1 output
1 = C1 V
0 = C1 V
CIS : Comparator Input Switch
When CM2:CM0: = 001 :
Then:
1 = C1 V
0 = C1 V
When CM2:CM0 = 010 :
Then:
1 = C1 V
0 = C1 V
Figure 7-2 shows the comparator modes and CM2:CM0 bit settings.
