CxNCH0
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 bit
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
01 = CxVP connects to DAC Voltage Reference (dac_ref)
10 = CxVP connects to FVR Voltage Reference (fvr_ref)
11 = CxVP connects to V
