The Fixed Voltage Reference, or FVR, is a stable
voltage reference, independent of V
2.048V or 4.096V selectable output levels. The output
of the FVR can be configured to supply a reference
voltage to the following:
• ADC input channel
• ADC positive reference
The FVR can be enabled by setting the FVREN bit of
the FVRCON register.

The output of the FVR supplied to the ADC module is
routed through two independent programmable gain
amplifiers. Each amplifier can be configured to amplify
the reference voltage by 1x, 2x or 4x, to produce the
three possible voltage levels.
The ADFVR<1:0> bits of the FVRCON register are
used to enable and configure the gain amplifier settings
for the reference supplied to the ADC module. Refer-

When the Fixed Voltage Reference module is enabled, it
requires time for the reference and amplifier circuits to
stabilize. Once the circuits stabilize and are ready for use,
the FVRRDY bit of the FVRCON register will be set. See
