0: The register is read/write.
1: The register is read-only, to protect against further accidental writes.
This bit is used for test purposes only.
0: The voltage regulator output is not pulled to ground.
1: The voltage regulator output has a pull-down to ground.
0: Regulator will enter deep mode in low-power sleep modes for lower power consumption.
1: Regulator will stay in full-power mode in all sleep modes for shorter start-up time.
This bit is set when the CALIB field has been updated by the Flash fuses after a reset.
0: The flash calibration will be redone after any reset.
1: The flash calibration will only be redone after a power-on reset.
Calibration value for Voltage Regulator. See Electrical Characteristics for voltage values.
0: The voltage regulator is currently disabled.
1: The voltage regulator is currently enabled.
This bit is read-only. Writing to this bit has no effect.
0: The voltage regulator is disabled or has not yet reached a stable output voltage.
1: The voltage regulator has reached the output voltage threshold level after being enabled.
This bit is read-only. Writing to this bit has no effect.
