8.11.5
The fixed voltage reference is independent of V
a nominal output voltage of 0.6V. This reference can be
enabled by setting the FVREN bit of the VRCON
register to ‘1’. This reference is always enabled when
the HFINTOSC oscillator is active.
8.11.6
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. See
the electrical specifications section for the minimum
delay requirement.

Multiplexers on the output of the voltage reference
module enable selection of either the CV
voltage reference for use by the comparators.
Setting the C1VREN bit of the VRCON register enables
current to flow in the CV
the CV
C1VREN bit selects the fixed voltage for use by C1.
Setting the C2VREN bit of the VRCON register enables
current to flow in the CV
the CV
C2VREN bit selects the fixed voltage for use by C2.
When both the C1VREN and C2VREN bits are cleared,
current flow in the CV
minimizing the power drain of the voltage reference
peripheral.
