8.3
There are eight modes of operation for the comparator.
The CMCON0 register is used to select these modes.
Figure 8-3 shows the eight possible modes.
If the Comparator mode is changed, the comparator
output level may not be valid for the specified mode
change delay shown in Section 15.0 “Electrical
Specifications”.
