17.0
The comparator voltage reference is a 16-tap resistor
ladder network that provides a selectable reference
voltage. Its purpose is to provide a reference for the
analog comparators.
A block diagram of the module is shown in Figure 17-1.
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
17.1
The voltage reference module is controlled through the
CVRCON register (Register 17-1). 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
