Voltage Reference
The comparator voltage reference module is controlled
through the CVRCON register (
through the CVRCON register (
). The
comparator voltage reference provides a range of
output voltages, with 32 distinct levels.
The comparator voltage reference supply voltage can
come from either V
output voltages, with 32 distinct levels.
The comparator voltage reference supply voltage can
come from either V
DD
and V
SS
, or the external V

-. The voltage source is selected by the
CVRSS bit (CVRCON<5>).
The settling time of the comparator voltage reference
must be considered when changing the CV
