The triple comparator module provides three dual input
comparators. The inputs to the comparator can be con-
figured to use any one of four external analog inputs, as
well as voltage reference inputs from the voltage
reference generator and band gap reference.

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 23-1. Diagrams of the possible individual
comparator configurations are shown in Figure 23-2.
Each comparator has its own control register,
CMxCON (Register 23-1), for enabling and configuring
its operation. The output and event status of all three
comparators are provided in the CMSTAT register
(Register 23-2).
