from the reference source; therefore, the CV

When the device wakes up from Sleep through an
interrupt or a Watchdog Timer time-out, the contents of
the CVRCON register are not affected. To minimize
current consumption in Sleep mode, the voltage
reference should be disabled.

A device Reset disables the voltage reference by
bit, CVROE (CVRCON<6>).
25.5
The voltage reference module operates independently
of the comparator module. The output of the reference
generator may be connected to the RF5 pin if the
CVROE bit is set. Enabling the voltage reference out-
put onto RF5 when it is configured as a digital input will
increase current consumption. Connecting RF5 as a
digital output, with CVRSS enabled, will also increase
current consumption.
The RF5 pin can be used as a simple D/A output with
limited drive capability. Due to the limited current drive
capability, a buffer must be used on the voltage
reference output for external connections to V
