A simplified circuit for an analog input is shown in
Figure 6-3. Since the analog pins are connected to a
digital output, they have reverse biased diodes to V

The comparator output, COUT, is read through the
CMCON register. This bit is read-only. The comparator
output may also be directly output to the RA2 pin in
three of the eight possible modes, as shown in
Figure 6-2. When in one of these modes, the output on
RA2 is asynchronous to the internal clock. Figure 6-4
shows the comparator output block diagram.
