This field must be written twice, first with key value 0x55, then 0xAA, for a write operation to have an effect.
Calibration value for Voltage Regulator. See Electrical Characteristics for voltage values.
Set to 1 when the CALIB field has been updated by the Flash fuses after power-on reset or when the Flash fuses are
reprogrammed. The CALIB field will not be updated again by the Flash fuses until a new power-on reset or the FCD field is
written to zero.
