C1ON: Comparator C1 Enable bit
1 = C1 Comparator is enabled
0 = C1 Comparator is disabled
C1OUT: Comparator C1 Output bit
If C1POL = 1 (inverted polarity):
If C1POL = 0 (non-inverted polarity):
C1OE: Comparator C1 Output Enable bit
1 = C1OUT is present on the RA2/AN2/T0CKI/INT/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
C1SP: Comparator C1 Speed Select bit
1 = C1 operates in normal speed mode
0 = C1 operates in low-power, slow speed mode
C1R: Comparator C1 Reference Select bit (non-inverting input)
1 = C1VP connects to C1V
0 = C1VP connects to RA0/AN0/C1IN+/ICSPDAT
C1CH<1:0>: Comparator C1 Channel Select bits
00 = C1VN of C1 connects to RA1/AN1/C12IN0-/V
01 = C1VN of C1 connects to RC1/AN5/C12IN1-/PH1
10 = C1VN of C1 connects to RC2/AN6/C12IN2-/OP2
11 = C1VN of C1 connects to RC3/AN7/C12IN3-/OP1

Note 1: C1OUT will only drive RA2/AN2/T0CKI/INT/C1OUT if: (C1OE = 1) and (C1ON = 1)
C1OUT = 1, C1VP < C1VN
C1OUT = 0, C1VP > C1VN
C1OUT = 1, C1VP > C1VN
C1OUT = 0, C1VP < C1VN
and (TRISA<2> = 0).
