The Fixed Voltage Reference, or FVR, is a stable voltage reference,
independent of V
DD, with the following 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
- Comparator input
- Digital-to-Analog Converter (DAC)
The FVR can be enabled by setting the FVREN bit of the FVRCON register.
Important: Fixed Voltage Reference output cannot exceed
VDD.
