C2ON
Comparator output requires the following three conditions: C2OE = 1, C2ON = 1 and corresponding
PORT TRIS bit = 0.
C2ON: Comparator C2 Enable bit
1 = Comparator C2 is enabled
0 = Comparator C2 is disabled
C2OUT: Comparator C2 Output bit
If C2POL = 1 (inverted polarity):
C2OUT = 0 when C2V
C2OUT = 1 when C2V
If C2POL = 0 (non-inverted polarity):
C2OUT = 1 when C2V
C2OUT = 0 when C2V
C2OE: Comparator C2 Output Enable bit
1 = C2OUT is present on C2OUT pin
0 = C2OUT 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’
C2R: Comparator C2 Reference Select bits (non-inverting input)
1 = C2V
0 = C2V
C2CH<1:0>: Comparator C2 Channel Select bits
00 = C2V
01 = C2V
10 = C2V
11 = C2V
