sPi register entries
Following table shows a list and declaration of failures:
The registers of the most significant byte and the lower part of the second byte contain the failure messages of
the transceiver (readable by the host controller). These are common failure messages as undervoltages at the sup-
ply pins (VCC, VIO), overtemperature, or permanent LOW at the TxEN as well as bus failures (bus line BP is shorted
to GND (BP2GND), BM is shorted to the supply voltage (VBAT) (BM2VSUP) a.s.o.).
A valid SPI access resets the failure entries as well as the INTN state.
The mode change due to a undervoltage at the supply voltage does not change the SPI registers.
