Note:
This byte is always clocked out (second SO-byte), except the SI control words says:
RD_SCON or RD_MUX. But: The content of the fault register will only be deleted if the control command
’RD_DIAG’ was clocked in and 16 clock pulses were counted.

Note: DIA_REG2 is always clocked out as first byte
F, OT Bit = 1: No Fault
F, OT Bit = 0: Fault, Over-temperature
The over-temperature bit is the latched result of an OR-operation out of the 6 signals of the
temperature sensor)
The general fault bit shows the fault occurrence at any of the outputs.
Reset of the Diagnostic Information
The diagnostic information will only be reset after the RD_DIAG command on the rising edge
of slave select or a reset signal is applied (RESET = low).
