12.0
The comparator module contains two analog compara-
tors. The inputs to the comparators are multiplexed
with I/O port pins RA0 through RA3, while the outputs
are multiplexed to pins RA4 and RA5. The on-chip volt-
age reference (Section 13.0 “Comparator Voltage
Reference Module”) can also be an input to the
comparators.
