9.1
There are eight modes of operation for the
comparators. The CMCON register is used to select
the mode. Figure 9-1 shows the eight possible modes.
The TRISA register controls the data direction of the
comparator pins for each mode. If the Comparator

be valid for the specified mode change delay shown
in Table 17-1.
Note:
Comparator interrupts should be disabled
during a Comparator mode change other-
wise a false interrupt may occur.
