CON COE CPOL EVPOL1 EVPOL0 CREF CCH1 CCH0

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 CON: Comparator Enable bit

1 = Comparator is enabled

0 = Comparator is disabled

bit 6 COE: Comparator Output Enable bit

1 = Comparator output is present on the CxOUT pin (assigned in PPS module)

0 = Comparator output is internal only

bit 5 CPOL: Comparator Output Polarity Select bit

1 = Comparator output is inverted

0 = Comparator output is not inverted

bit 4-3 EVPOL<1:0>: Interrupt Polarity Select bits

11 = Interrupt generation on any change of the output

(1)

10 = Interrupt generation only on high-to-low transition of the output

01 = Interrupt generation only on low-to-high transition of the output

00 = Interrupt generation is disabled

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

1 = Non-inverting input connects to internal CVREF voltage

0 = Non-inverting input connects to CxINA pin

bit 1-0 CCH<1:0>: Comparator Channel Select bits

11 = Inverting input of comparator connects to V

IRV

10 = For CM1CON, inverting input of comparator connects to C2INB pin; for CM2CON, reserved

01 = Reserved

00 = Inverting input of comparator connects to CxINB pin

Note 1: The CMxIF is automatically set any time this mode is selected and must be cleared by the application after

the initial configuration.
