Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
CMON: Comparator Enable bit
1 = Comparator is enabled
0 = Comparator is disabled
bit 6
COUT: Comparator Output bit
If C1POL = 1 (inverted polarity):
COUT = 0 when CMVIN+ > CMVIN-
COUT = 1 when CMVIN+ < CMVIN-
If C1POL = 0 (non-inverted polarity):
COUT = 1 when CMVIN+ > CMVIN-
COUT = 0 when CMVIN+ < CMVIN-
bit 5
CMOE: Comparator Output Enable bit
1 = COUT is present on the COUT pin(1)
0 = COUT is internal only
bit 4
CMPOL: Comparator Output Polarity Select bit
1 = COUT logic is inverted
0 = COUT logic is not inverted
bit 3
Unimplemented: Read as ‘0’
bit 2
CMR: Comparator Reference Select bit (non-inverting input)
1 = CMVIN+ connects to CMVREF output
0 = CMVIN+ connects to CIN+ pin
bit 1
Unimplemented: Read as ‘0’
bit 0
CMCH: Comparator C1 Channel Select bit
0 = CMVIN- pin of the Comparator connects to CIN0-
1 = CMVIN- pin of the Comparator connects to CIN1-
Note 1: Comparator output requires the following three conditions: CMOE = 1, CMON = 1 and corresponding port
TRIS bit = 0.
