23.1.1
The voltage reference module is controlled through the
CVRCON register (Register 23-2). The comparator
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
V
bit (CVRCON<4>).
The settling time of the comparator voltage reference
must be considered when changing the CV
output.
