The RSTB bit is cleared after a read & clear of all the specific bits in the status registers, which caused the reset

event.

SPI error (SPIE)

The SPIE is a logical OR combination of errors related to a wrong SPI communication.

Physical layer error (PLE)

The PLE is a logical OR combination of errors related to the LIN and CAN FD transceivers.

Functional error (FE)

The FE is a logical OR combination of errors coming from functional blocks (for example, high-side over current).

Device error (DE)

The DE is a logical OR combination of errors related to device specific blocks (for example, VS over voltage, over

temperature.

Global warning (GW)

The GW is a logical OR combination of warning flags (for example, thermal warning).

Fail-safe (FS)

The FS bit indicates that the device was forced into a safe state due to mistreatment or fundamental internal

errors (for example, watchdog failure, voltage regulator failure).

4.2.2.7

Data-out payload

The payload (data bytes 1 to 3) is the data transferred from the slave device with every SPI communication to

the master device. The Payload always follows the OpCode and the address bits of the actual shifted in data

(In-frame-Response).
