There are eight modes of operation for the comparator.
The CMCON register, shown in Register 6-1, is used to
select the mode. Figure 6-2 shows the eight possible
modes. The TRISA register controls the data direction
of the comparator pins for each mode. If the

Comparator interrupts should be disabled
during a Comparator mode change. Other-
wise, a false interrupt may occur.
