7.4.1 Internal Diagnosis Register (Status Register and Shadow Register)
If the diagnosis happens during the SPI communication, the function follows this protocol:
The diagnosis information is stored in the shadow register when the diagnosis happens.
After the output of the previous information a new diagnosis is sent from the shadow to the status register,
and both registers are output through the DOUT pin.
In this case, a FAULT signal continues to be output until a new diagnosis is read by the CPU.
All diagnosis bits read by the DIAG_READ1 command happen before the CS falling edge. So, all the diagnosis
events that happen right after the CS falling edge are not read by the current DIAG_READ1 command, instead
they are read by the next DIAG_READ1 command.
