CxNCH<1:0>

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(1)

01 = CxVP connects to DAC Voltage Reference

10 = CxVP connects to FVR Voltage Reference

For C1:

11 = CxVP connects to C12IN+ pin

For C2:

11 = CxVP connects to VSS

bit 3-2

Unimplemented: Read as ‘0’

bit 1-0

CxNCH<1:0>: Comparator Negative Input Channel Select bits

00 = CxVN connects to C12IN0- pin

01 = CxVN connects to C12IN1- pin

10 = CxVN connects to C12IN2- pin

11 = CxVN connects to C12IN3- pin

Note 1:

CxVP connects to C12IN+ pin when using Comparator 2.
