3 Fast Bring-up Sequence

During first time bring-up, the result of the calibration is saved to the on-chip non-volatile (fuse) memory. Calibration Results are then loaded from fuse memory for subsequent bring-ups. Fuse blow is One-Time-Process, that is done during customer factory calibration when all system parameters are finalized. Faster bring-up time is achieved (368ms) at the cost of flexibility of input parameters.
