30 FVR - Fixed Voltage Reference
The Fixed Voltage Reference (FVR) is a stable voltage reference,
independent of VDD, with the following selectable output levels:
- 1.024V
- 2.048V
- 4.096V
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.
