COMPARATOR MODULE
The comparator module contains two analog com-
parators.
The
inputs
to
the
comparators
are
multiplexed with I/O port pins, RA0 through RA3, while
the outputs are multiplexed to pins RA4 and RA5. The
on-chip voltage reference (Section 14.0 “Comparator
Voltage Reference Module”) can also be an input to
the comparators.
The CMCON register (Register 13-1) controls the
comparator input and output multiplexers. A block
diagram of the various comparator configurations is
shown in Figure 13-1.

bit 0
bit 7
C2OUT: Comparator 2 Output bit
When C2INV = 0:
1
= C2 VIN+ > C2 VIN-
0
= C2 VIN+ < C2 VIN-
When C2INV = 1:
1
= C2 VIN+ < C2 VIN-
0
= C2 VIN+ > C2 VIN-
bit 6
C1OUT: Comparator 1 Output bit
When C1INV = 0:
1
= C1 VIN+ > C1 VIN-
0
= C1 VIN+ < C1 VIN-
When C1INV = 1:
1
= C1 VIN+ < C1 VIN-
0
= C1 VIN+ > C1 VIN-
bit 5
C2INV: Comparator 2 Output Inversion bit
1
= C2 output inverted
0
= C2 output not inverted
bit 4
C1INV: Comparator 1 Output Inversion bit
1
= C1 output inverted
0
= C1 output not inverted
bit 3
CIS: Comparator Input Switch bit
When CM2:CM0 = 110:
1
=C1 VIN- connects to RA3/AN3
C2 VIN- connects to RA2/AN2
0
=C1 VIN- connects to RA0/AN0
C2 VIN- connects to RA1/AN1
bit 2-0
CM2:CM0: Comparator Mode bits
Figure 13-1 shows the Comparator modes and CM2:CM0 bit settings.
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
