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 Register 8-1, controls
the comparator input and output multiplexers. A block
diagram of the comparator is shown in Figure 8-1.

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
bit 2-0:
CM<2:0>: Comparator mode
