Legend:
R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets
q = Value depends on condition

FVREN: Fixed Voltage Reference Enable bit
1 = Fixed Voltage Reference is enabled
0 = Fixed Voltage Reference is disabled
FVRRDY: Fixed Voltage Reference Ready Flag bit(1)
1 = Fixed Voltage Reference output is ready for use
0 = Fixed Voltage Reference output is not ready or not enabled
TSEN: Temperature Indicator Enable bit(3)
1 = Temperature Indicator is enabled
0 = Temperature Indicator is disabled
TSRNG: Temperature Indicator Range Selection bit(3)
1 = VOUT = VDD - 4VT (High Range)
0 = VOUT = VDD - 2VT (Low Range)
Unimplemented: Read as ‘0 ‘
ADFVR<1:0>: ADC Fixed Voltage Reference Selection bit
11 = ADC Fixed Voltage Reference Peripheral output is 4x (4.096V)(2)
10 = ADC Fixed Voltage Reference Peripheral output is 2x (2.048V)(2)
01 = ADC Fixed Voltage Reference Peripheral output is 1x (1.024V)
00 = ADC Fixed Voltage Reference Peripheral output is off.

FVRRDY indicates the true state of the FVR.
Fixed Voltage Reference output cannot exceed VDD.
See Section 14.0 “Temperature Indicator Module” for additional information.
