22.1
Comparator Configuration
There are eight modes of operation for the compara-
tors, shown in Figure 22-1. Bits CM2:CM0 of the
CMCON register are used to select these modes. The
TRISA register controls the data direction of the
comparator pins for each mode. If the Comparator
mode is changed, the comparator output level may not
be valid for the specified mode change delay shown in
Section 28.0 “Electrical Characteristics”.

COMPARATOR I/O OPERATING MODES
Note:
Comparator interrupts should be disabled

change.
Otherwise, a false interrupt may occur.
