COMPARATOR MODULE
The Comparator module contains two analog
comparators. The inputs to the comparators are
multiplexed with the RA0 through RA3 pins. The On-
chip Voltage Reference (Section 10.0) can also be an
input to the comparators.
The CMCON register, shown in Register 9-1, controls
the comparator input and output multiplexers. A block
diagram of the comparator is shown in Figure 9-1.
