* The flashing algorithm runs from RAM, reading from a register to which this function writes to. The algorithm is open loop, there is no control to verify that the FM read the register before writing the next data. A closed loop approach was much slower, and the current implementation does not fail, and if it did the crc check would detect it, allowing to flash again.
