bit 7

bit 0

Legend:
R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

u = Bit is unchanged

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

bit 7

CxINTP:

Comparator Interrupt on Positive Going Edge Enable bits

1 = The CxIF interrupt flag will be set upon a positive going edge of the CxOUT bit
0 = No interrupt flag will be set on a positive going edge of the CxOUT bit

bit 6

CxINTN:

Comparator Interrupt on Negative Going Edge Enable bits

1 = The CxIF interrupt flag will be set upon a negative going edge of the CxOUT bit
0 = No interrupt flag will be set on a negative going edge of the CxOUT bit

bit 5-4

CxPCH<1:0>:

Comparator Positive Input Channel Select bits

00 = CxVP connects to CxIN+ pin
