Comparator Configuration
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 mode is changed, the comparator output
level may not be valid for a specified period of time.
Refer to the specifications in Section 12.0 “Electri-

COMPARATOR I/O OPERATING MODES
Note:
Comparator interrupts should be disabled
during a Comparator mode change. Other-
wise, a false interrupt may occur.
