21.2
The FVR reference is a stable fixed voltage reference,
independent of V
1.2V. This reference can be enabled by setting the
FVREN bit of the CVRCON2 register to ‘1’. The FVR
defaults to on when any one or more of the HFINTOSC,
HLVD, or BOR functions are enabled. The FVR voltage
reference can be routed to the comparators or an ADC
input channel.

When the Fixed Voltage Reference module is enabled, it
will require some time for the reference and its amplifier
circuits to stabilize. The user program must include a
small delay routine to allow the module to settle. The
FVRST stable bit of the CVRCON2 register also indicates
that the FVR reference has been operating long enough
