C1ON
C1ON: Comparator Enable bit
1 = Comparator is enabled and consumes no active power
0 = Comparator is disabled
C1OUT: Comparator Output bit
If C1POL = 1 (inverted polarity):
1 = C1VP < C1VN
0 = C1VP > C1VN
If C1POL = 0 (non-inverted polarity):
1 = C1VP > C1VN
0 = C1VP < C1VN
C1OE: Comparator Output Enable bit
1 = C1OUT is present on the C1OUT pin. Requires that the associated TRIS bit be cleared to actually
0 = C1OUT is internal only
C1POL: Comparator Output Polarity Select bit
1 = Comparator output is inverted
0 = Comparator output is not inverted
Unimplemented: Read as ‘0’
C1SP: Comparator Speed/Power Select bit
1 = Comparator operates in normal power, higher speed mode
0 = Comparator operates in low-power, low-speed mode
C1HYS: Comparator Hysteresis Enable bit
1 = Comparator hysteresis enabled
0 = Comparator hysteresis disabled
C1SYNC: Comparator Output Synchronous Mode bit
1 = Comparator output to Timer1 and I/O pin is synchronous to changes on Timer1 clock source.
0 = Comparator output to Timer1 and I/O pin is asynchronous.
C1OUT

Output updated on the falling edge of Timer1 clock source.
