CxINTP CxINTN CxPCH<2:0> CxNCH<2:0>
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 5-3
CxPCH<2:0>: Comparator Positive Input Channel Select bits
111 = CxVP connects to AGND
110 = CxVP connects to FVR Buffer 2
101 = CxVP connects to V
DAC
100 = CxVP inconnected, input floating
011 = CxVP inconnected, input floating
010 = CxVP inconnected, input floating
001 = CxVP connects to CxIN1+ pin
000 = CxVP connects to CxIN0+ pin
bit 2-0
CxNCH<2:0>: Comparator Negative Input Channel Select bits
111 = CxVN connects to AGND
110 = CxVN unconnected, input floating
101 = CxVN unconnected, input floating
100 = CxVN connects to CxIN4- pin(1)
