FVRRDY is always ‘1’ on devices with LDO (PIC16F193X).
Fixed Voltage Reference output cannot exceed V
Shaded cells are not used with the Fixed Voltage Reference.
FVREN: Fixed Voltage Reference Enable bit
0 = Fixed Voltage Reference is disabled
1 = Fixed Voltage Reference is enabled
FVRRDY: Fixed Voltage Reference Ready Flag bit
0 = Fixed Voltage Reference output is not ready or not enabled
1 = Fixed Voltage Reference output is ready for use
Reserved: Read as ‘0’. Maintain these bits clear.
CDAFVR<1:0>: Comparator and DAC Fixed Voltage Reference Selection bit
00 = Comparator and DAC Fixed Voltage Reference Peripheral output is off.
01 = Comparator and DAC Fixed Voltage Reference Peripheral output is 1x (1.024V)
10 = Comparator and DAC Fixed Voltage Reference Peripheral output is 2x (2.048V)
11 = Comparator and DAC Fixed Voltage Reference Peripheral output is 4x (4.096V)
ADFVR<1:0>: ADC Fixed Voltage Reference Selection bit
00 = ADC Fixed Voltage Reference Peripheral output is off.
01 = ADC Fixed Voltage Reference Peripheral output is 1x (1.024V)
10 = ADC Fixed Voltage Reference Peripheral output is 2x (2.048V)
