19.0
The comparator voltage reference is a 16-tap resistor
ladder network that provides a selectable reference
voltage. Although its primary purpose is to provide a
reference for the analog comparators, it may also be
used independently of them.
A block diagram of the module is shown in Figure 19-1.
The resistor ladder is segmented to provide two ranges
of CV
conserve power when the reference is not being used.
The module’s supply reference can be provided from
either device V
19.1
The voltage reference module is controlled through the
CVRCON register (Register 19-1). The comparator
voltage reference provides two ranges of output
voltage, each with 16 distinct levels. The range to be

primary difference between the ranges is the size of the
steps

The equations used to calculate the output of the
comparator voltage reference are as follows:

The settling time of the comparator voltage reference
