Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
C1OUT: Comparator Output bit
1 = VIN+ > VIN-
0 = VIN+ < VIN-
bit 6
C1OUTEN: Comparator Output Enable bit^{(1), (2)}
1 = Output of comparator is NOT placed on the C1OUT pin
0 = Output of comparator is placed in the C1OUT pin
bit 5
C1POL: Comparator Output Polarity bit⁽²⁾
1 = Output of comparator is not inverted
0 = Output of comparator is inverted
bit 4
C1T0CS: Comparator TMR0 Clock Source bit⁽²⁾
1 = TMR0 clock source selected by T0CS control bit
0 = Comparator output used as TMR0 clock source
bit 3
C1ON: Comparator Enable bit
1 = Comparator is on
0 = Comparator is off
bit 2
C1NREF: Comparator Negative Reference Select bit⁽²⁾
1 = C1IN- pin
0 = 0.6V VREF
bit 1
C1PREF: Comparator Positive Reference Select bit⁽²⁾
1 = C1IN+ pin
0 = C1IN- pin
bit 0
C1WU: 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 T0CS bit for TRIS control of RB2.
2: When comparator is turned on, these control bits assert themselves. Otherwise, the other registers have
precedence.
