The Comparator Voltage Reference is a 16-tap resistor
ladder network that provides a selectable voltage refer-
ence. The resistor ladder is segmented to provide two
ranges of CV
tion to conserve power when the reference is not being
used. The CVRCON register controls the operation of
the reference as shown in Register 20-1. The block dia-
gram is given in Figure 20-1.
The comparator reference supply voltage can come
from either V
V
comparator reference supply voltage is controlled by
the CVRSS bit.

The Comparator Voltage Reference can output 16 dis-
tinct voltage levels for each range. The equations used
to calculate the output of the Comparator Voltage Ref-
erence are as follows:
The settling time of the Comparator Voltage Reference
must be considered when changing the CV
(Section 25.0).
