Comparator Configuration
There are eight modes of operation for the comparators. The CMCON register is used to select
the mode.
direction of the comparator I/O pins for each mode. If the comparator mode is changed, the com-
parator output level may not be valid for the new mode for the delay specified in the electrical
specifications of the device.
