COMPARATOR MODULE

The Comparator module provides a set of dual input

comparators. The inputs to the comparator can be con-

figured to use any one of the four pin inputs (C1IN+,

C1IN-, C2IN+ and C2IN-) as well as the Comparator

Voltage Reference Input (CVREF).

2: Some registers

and

associated bits

described in this section may not be avail-

able on all devices. Refer to Section 4.0

“Memory Organization” in this data

sheet for device-specific register and bit

information.

Note:

This peripheral contains output func-

tions that may need to be configured by
