C1INTP: Comparator Interrupt on Positive Going Edge Enable bits
1 = The C1IF interrupt flag will be set upon a positive going edge of the C1OUT bit
0 = No interrupt flag will be set on a positive going edge of the C1OUT bit
C1INTN: Comparator Interrupt on Negative Going Edge Enable bits
1 = The C1IF interrupt flag will be set upon a negative going edge of the C1OUT bit
0 = No interrupt flag will be set on a negative going edge of the C1OUT bit
C1PCH<1:0>: Comparator Positive Input Channel Select bits
00 = C1VP connects to C1IN+ pin
01 = C1VP connects to DAC Voltage Reference
10 = C1VP connects to FVR Voltage Reference
Unimplemented: Read as ‘0’
C1NCH: Comparator Negative Input Channel Select bit
0 = C1VN connects to C1IN0- pin
1 = C1VN connects to C1IN1- pin
