R/W-0
Note 1:
FVR1EN: Fixed Voltage Reference 1 Enable bit
0 = FVR is disabled
1 = FVR is enabled
FVR1ST: Fixed Voltage Reference 1 Stable bit
0 = FVR is not stable
1 = FVR is stable
FVR1S<1:0>: Fixed Voltage Reference 1 Voltage Select bits
00 = Reserved, do not use
01 = 1.024V (x1)
10 = 2.048V (x2)
11 = 4.096V (x4)
Unimplemented: Read as ‘0’
R is dependent upon the voltage reference Configuration bits, CVR<3:0> and CVRR.
