Comparator output requires the following three conditions: C1OE = 1, C1ON = 1 and corresponding
PORT TRIS bit = 0.
C1ON: Comparator C1 Enable bit
1 = Comparator C1 is enabled
0 = Comparator C1 is disabled
C1OUT: Comparator C1 Output bit
If C1POL = 1 (inverted polarity):
C1OUT = 0 when C1V
C1OUT = 1 when C1V
If C1POL = 0 (non-inverted polarity):
C1OUT = 1 when C1V
C1OUT = 0 when C1V
C1OE: Comparator C1 Output Enable bit
1 = C1OUT is present on the C1OUT pin
0 = C1OUT is internal only
C1POL: Comparator C1 Output Polarity Select bit
1 = C1OUT logic is inverted
0 = C1OUT logic is not inverted
Unimplemented: Read as ‘0’
C1R: Comparator C1 Reference Select bit (non-inverting input)
1 = C1V
0 = C1V
C1CH<1:0>: Comparator C1 Channel Select bit
00 = C1V
01 = C1V
10 = C1V
11 = C1V
