24.1
The comparator voltage reference module is controlled
through the CVRCON register (Register 24-1). 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 selected by the CV
(CVR<3:0>), with one range offering finer resolution.
The comparator reference supply voltage can come
from either V
V
(CVRCON<4>).
The settling time of the comparator voltage reference
must be considered when changing the CV
