The control and diagnosis function of the TLE7237GS is based on two register banks which are accessed via
following SPI protocol. The control register bank contains eight registers (with 4 bit each) addressed by a 3 bit
pointer. The diagnosis register bank contains four registers (with 4 bit each) addressed by a 2 bit pointer. An
additional indication bit is available to differentiate between standard diagnosis information and data read from a
register bank.
