Serial Peripheral Interface
Note:
The min. On-time during PWM is limited by the actual Ton and Toff time of the respective HS switch,
e.g. the PWM setting ‘000 0001’ could not be realized.
Notes
1. The
SYS_STATUS_CTRL
register is an exception for the default values, i.e. it will keep its configured value also
after a Soft Reset.
2. This byte is intended for storing system configurations of the ECU by the microcontroller and is only accessible
in SBC Normal Mode. The byte is not accessible by the SBC and is also not cleared after Fail-Safe or SBC
Restart Mode. It allows the microcontroller to quickly store system configuration without loosing the data.
