PIC24FV32KA304 FAMILY
24.0 COMPARATOR VOLTAGE
REFERENCE
24.1 Configuring the Comparator
Voltage Reference
The comparator voltage reference module is controlled
through the CVRCON register (Register 24-1). 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
DD
and V
SS
or the external V
REF
+
and V
REF
-. 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
REF
output.
