C1ON C1OUT C1OE C1POL C1SP C1R C1CH1 C1CH0

bit 7 bit 0

Legend:

R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’

-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown

bit 7 C1ON: Comparator C1 Enable bit

1 = C1 Comparator is enabled

0 = C1 Comparator is disabled

bit 6 C1OUT: Comparator C1 Output bit

If C1POL =

1 (inverted polarity):

C1OUT = 1, C1VP < C1VN

C1OUT = 0, C1VP > C1VN

If C1POL =

0 (non-inverted polarity):

C1OUT = 1, C1VP > C1VN

C1OUT = 0, C1VP < C1VN

bit 5 C1OE: Comparator C1 Output Enable bit

1 = C1OUT is present on the RA2/AN2/T0CKI/INT/C1OUT pin

(1)

0 = C1OUT is internal only

bit 4 C1POL: Comparator C1 Output Polarity Select bit

1 = C1OUT logic is inverted

0 = C1OUT logic is not inverted

bit 3 C1SP: Comparator C1 Speed Select bit

1 = C1 operates in normal speed mode

0 = C1 operates in low-power, slow speed mode

bit 2 C1R: Comparator C1 Reference Select bit (non-inverting input)

1 = C1VP connects to C1V

REF output

0 = C1VP connects to RA0/AN0/C1IN+/ICSPDAT

bit 1-0 C1CH<1:0>: Comparator C1 Channel Select bits

00 = C1VN of C1 connects to RA1/AN1/C12IN0-/V

REF/ICSPCLK

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) and (TRISA<2> = 0).
