21.0
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 21-1. The block
diagram is given in Figure 21-1.
The comparator reference supply voltage comes from

The comparator voltage reference can output 16 distinct
voltage levels for each range. The equations used to cal-
culate the output of the comparator voltage reference
are as follows:
EQUATION 21-1:
The settling time of the comparator voltage reference
must be considered when changing the CV
output (see Table 26-2 in Section 26.0 “Electrical
Characteristics”).
