21.2
The FVR reference is a stable fixed voltage reference,
independent of V
1.024V. This reference can be enabled by setting the
FVR1EN bit of the REFCON0 register to ‘1’. 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
FVR1ST stable bit of the REFCON0 register also
indicates that the FVR reference has been operating long
enough to be stable. See
