CM<2:0> = 010 -> 2 independent comparators (=op amps).
CM<2:0> = 100 -> 2 common reference comparators (=op amps).

AN0 and AN3 & AN1 and AN2 are input pins for op amps and C1OUT and C2OUT are respectively output pins (see FIGURE: COMPARATOR I/O OPERATING MODES).

Use those like conventional op amps.
