24.1.1
The voltage reference module is controlled through the
CVRCON register
voltage reference provides two ranges of output
voltage, each with 16 distinct levels. The range to be
used is selected by the CVRR bit (CVRCON<5>). The
primary difference between the ranges is the size of the
steps
(CVR3:CVR0), with one range offering finer resolution.

The comparator reference supply voltage can come
from either V

bit (CVRCON<4>).
The settling time of the comparator voltage reference
must be considered when changing the CV
