C1INTP
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
