The CMPxIF bit is automatically set any time this mode is selected and must be cleared by the application
after the initial configuration.
Comparators, 1 and 3, use C2INB as an input to the inverting terminal; Comparator 2 uses C2IND.
C1INC, C2INC and C2IND are all unavailable for 64-pin devices (PIC18F6XK90).
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
0 = Comparator output is internal only
CPOL: Comparator Output Polarity Select bit
1 = Comparator output is inverted
0 = Comparator output is not inverted
EVPOL<1:0>: Interrupt Polarity Select bits
11 = Interrupt generation on any change of the output
10 = Interrupt generation only on high-to-low transition of the output
01 = Interrupt generation only on low-to-high transition of the output
00 = Interrupt generation is disabled
CREF: Comparator Reference Select bit (non-inverting input)
1 = Non-inverting input connects to the internal CV
0 = Non-inverting input connects to the CxINA pin
CCH<1:0>: Comparator Channel Select bits
11 = Inverting input of the comparator connects to V
10 = Inverting input of the comparator connects to the C2INB or C2IND pin
01 = Inverting input of the comparator connects to the CxINC pin
00 = Inverting input of the comparator connects to the CxINB pin
