Calibration Value for the RC oscillator.
Set to 1 when CTRL, HYST, and LEVEL fields have been updated by the Flash fuses after power-on reset, or after Flash fuses
are reprogrammed. The CTRL, HYST and LEVEL values will not be updated again by the Flash fuses until a new power-on
reset or the FCD field is written to zero.
This field must be written twice, first with key value 0x55, then 0xAA, for a write operation to have an effect.
