Comparator output requires the following three conditions: CMOE = 1, CMON = 1 and corresponding port
TRIS bit = 0.
CMON: Comparator Enable bit
1 = Comparator is enabled
0 = Comparator is disabled
COUT: Comparator Output bit
If C1POL = 1 (inverted polarity):
COUT = 0 when CMV
COUT = 1 when CMV
If C1POL = 0 (non-inverted polarity):
COUT = 1 when CMV
COUT = 0 when CMV
CMOE: Comparator Output Enable bit
1 = COUT is present on the COUT pin
0 = COUT is internal only
CMPOL: Comparator Output Polarity Select bit
1 = COUT logic is inverted
0 = COUT logic is not inverted
Unimplemented: Read as ‘0’
CMR: Comparator Reference Select bit (non-inverting input)
1 = CMV
0 = CMV
Unimplemented: Read as ‘0’
CMCH: Comparator C1 Channel Select bit
00 = CMV
01 = CMV
COUT
