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 10.0) can also be an
input to the comparators.
The CMCON register, shown in Register 9-1, controls
the comparator input and output multiplexers. A block
diagram of the comparator is shown in Figure 9-1.
REGISTER 9-1:
CMCON REGISTER (ADDRESS: 01Fh)

bit 7
bit 0
bit 7
C2OUT: Comparator 2 Output
When C2INV = 0:
1
= C2 V
IN+ > C2 VIN-
0
= C2 V
IN+ < C2 VIN-
When C2INV = 1:
1
= C2 V
IN+ < C2 VIN-
0
= C2 V
IN+ > C2 VIN-
bit 6
C1OUT: Comparator 1 Output
When C1INV = 0:
1
= C1 V
IN+ > C1 VIN-
0
= C1 V
IN+ < C1 VIN-
When C1INV = 1:
1
= C1 V
IN+ < C1 VIN-
0
= C1 V
IN+ > C1 VIN-
bit 5
C2INV: Comparator 2 Output Inversion
1
= C2 Output inverted
0
= C2 Output not inverted
bit 4
C1INV: Comparator 1 Output Inversion
1
= C1 Output inverted
0
= C1 Output not inverted
bit 3
CIS: Comparator Input Switch
When CM2:CM0: = 001
Then:
1
= C1 V
IN- connects to RA3
0
= C1 V
IN- connects to RA0
When CM2:CM0 = 010
Then:
1
= C1 V
IN- connects to RA3
C2 V
IN- connects to RA2
0
= C1 V
IN- connects to RA0
C2 V
IN- connects to RA1
bit 2-0
CM2:CM0: Comparator Mode
Figure 9-1 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
