my Fullscale Register and my conf Register dont really work.
if i Write 0x108808 into the config register the adc gets into Fullscale system calibration mode and doesnt leave this mode.
if i dont change the second byte of the config register the adc doesnt do this.
if i read the fullscale Register, i get fhe value 0xFFFFF0
and if i read the data register i get different values.
Set Mode to 0x180001
Read Mode Register --> 0x188801
Set Conf to 0x108808
Read Conf Register --> 0xFF8808
Read Fullscale Regiser -- 0xFFFFF0
