8.0 COMPARATOR MODULE

The comparator module contains two analog

comparators. The inputs to the comparators are

multiplexed with the RA0 through RA3 pins. The

on-chip Voltage Reference (Section 9.0) can also be an

input to the comparators.

The CMCON register, shown in Figure 8-1, controls the

comparator input and output multiplexers. A block

diagram of the comparator is shown in Figure 8-2.

bit 7:

C2OUT: Comparator 2 output

1 = C2 VIN+ > C2 VIN–

0 = C2 VIN+ < C2 VIN–

bit 6:

C1OUT: Comparator 1 output

1 = C1 VIN+ > C1 VIN–

0 = C1 VIN+ < C1 VIN–

bit 5-4: Unimplemented: Read as '0'

bit 3:

CIS: Comparator Input Switch

When CM<2:0>: = 001:

1 = C1 VIN– connects to RA3

0 = C1 VIN– connects to RA0

When CM<2:0> = 010:

1 = C1 VIN– connects to RA3

C2 VIN– connects to RA2

0 = C1 VIN– connects to RA0

C2 VIN– connects to RA1
