This field must be written twice, first with key value 0x55, then 0xAA, for a write operation to have an effect.
Calibration Value for the RC oscillator.
Set to 1 when the CALIB field has been updated by the Flash fuses after power-on reset or Flash fuses update.
0: Allow subsequent overwriting of the CALIB value by Flash fuses.
1: The CALIB value will not be updated again by Flash fuses.
