bit 7
CON:
Comparator Enable bit
1
= Comparator is enabled
0
= Comparator is disabled

COE:
Comparator Output Enable bit
1
= Comparator output is present on the CxOUT pin (assigned in PPS module)
0
= Comparator output is internal only
bit 5
CPOL:
Comparator Output Polarity Select bit
1
= Comparator output is inverted
0
= Comparator output is not inverted
