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 C2OUT: Comparator Output bit

1 = V

IN+ > VIN-

0 = V

IN+ < VIN-

bit 6 C2OUTEN

: Comparator Output Enable bit

(1), (2)

1 = Output of comparator is NOT placed on the C2OUT pin

0 = Output of comparator is placed in the C2OUT pin

bit 5 C2POL: Comparator Output Polarity bit

(2)

1 = Output of comparator not inverted

0 = Output of comparator inverted

bit 4 C2PREF2: Comparator Positive Reference Select bit

(2)

1 = C1IN+ pin

0 = C2IN- pin

bit 3 C2ON: Comparator Enable bit

1 = Comparator is on

0 = Comparator is off

bit 2 C2NREF: Comparator Negative Reference Select bit

(2)

1 = C2IN- pin

0 = CV

REF

bit 1 C2PREF1: Comparator Positive Reference Select bit

(2)

1 = C2IN+ pin

0 = C2PREF2 controls analog input selection

bit 0 C2WU

: Comparator Wake-up on Change Enable bit

(2)

1 = Wake-up on Comparator change is disabled

0 = Wake-up on Comparator change is enabled.

Note 1: Overrides TOCS bit for TRIS control of RC4.

2: When comparator is turned on, these control bits assert themselves. Otherwise, the other registers have

precedence.
