17.8 Register Definitions: Comparator Control
REGISTER 17-1: CMxCON0: COMPARATOR Cx CONTROL REGISTER 0

CxON CxOUT CxOE CxPOL — CxSP CxHYS CxSYNC
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit
u = Bit is unchanged x = Bit is unknown U = Unimplemented bit, read as ‘0’
‘1’ = Bit is set ‘0’ = Bit is cleared -n/n = Value at POR and BOR/Value at all other Resets
bit 7 CxON: Comparator Enable bit
1 = Comparator is enabled
0 = Comparator is disabled and consumes no active power
bit 6 CxOUT: Comparator Output bit
If CxPOL =
1 (inverted polarity):
1 = CxVP < CxVN
0 = CxVP > CxVN
If CxPOL =
0 (non-inverted polarity):
1 = CxVP > CxVN
0 = CxVP < CxVN
bit 5 CxOE: Comparator Output Enable bit
1 = CxOUT is present on the CxOUT pin; requires that the associated TRISx bit be cleared to actually
drive the pin, not affected by CxON
0 = CxOUT is internal only
bit 4 CxPOL: Comparator Output Polarity Select bit
1 = Comparator output is inverted
0 = Comparator output is not inverted
bit 3 Unimplemented: Read as ‘0’
bit 2 CxSP: Comparator Speed/Power Select bit
1 = Comparator mode is in Normal Power, Higher Speed mode
0 = Comparator mode is in Low-Power, Low-Speed mode
bit 1 CxHYS: Comparator Hysteresis Enable bit
1 = Comparator hysteresis is enabled
0 = Comparator hysteresis is disabled
bit 0 CxSYNC: Comparator Output Synchronous Mode bit
1 = Comparator output to Timer1 and I/O pin is synchronous to changes on Timer1 clock source;
output updated on the falling edge of Timer1 clock source
0 = Comparator output to Timer1 and I/O pin is asynchronous
