Comparator Configuration
There are eight modes of operation for the
comparators. The CMCON register is used to select the
mode. Figure 7-2 shows the eight possible modes. The
TRISA register controls the data direction of the com-
parator 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
Table 12-2.
Note:
Comparator interrupts should be disabled
during a comparator mode change other-
wise a false interrupt may occur.
