The triple comparator module provides three dual input
comparators. The inputs to the comparator can be
configured to use any one of five external analog inputs
(CxINA, CxINB, CxINC, CxIND and V
voltage reference input from one of the internal band
gap references or the comparator voltage reference
generator (V

The comparator outputs may be directly connected to
the CxOUT pins. When the respective COE equals ‘1’,
the I/O pad logic makes the unsynchronized output of
the comparator available on the pin.
A simplified block diagram of the module in shown in
Figure 24-1. Diagrams of the possible individual
comparator configurations are shown in Figure 24-2.
Each comparator has its own control register,
CMxCON (Register 24-1), for enabling and configuring
its operation. The output and event status of all three
comparators is provided in the CMSTAT register
(Register 24-2).
