The comparator voltage reference is a 16-tap resistor
ladder network that provides a selectable voltage
reference. The resistor ladder is segmented to provide
two ranges of CV
function to conserve power when the reference is not
being used.

The comparator voltage reference can output 16
distinct voltage levels for each range. The equations
used to calculate the output of the comparator voltage
reference are as follows:
