The SPI protocol of the SPIDER - TLE 7240SL provides two registers. The input register and the diagnosis
register. The diagnosis register contains four pairs of diagnosis flags, the input register contains the input
multiplexer configuration. After power-on reset, all register bits are set to 1 and the device is in idle mode.
