1) WD “off” when voltage-regulator output current below “watchdog disable current threshold”
2) WD default “off” in SBC Stop / Sleep Mode; WD can be active in order to generate period wake-ups of SBC
3) “ON / OFF” state is inherited from previous operating mode (“OFF” after POR and RESET)
The System-Basis-Chip (SBC) offers several operation modes that are controlled via three mode select bits MS0,
MS1 and MS2 within the SPI: SBC Active, Sleep and Stop mode, as well as LIN Receive-Only mode.
An overview of the operating modes and the operating mode transitions is indicated in
Note: It is possible to directly change from Stand-By to Stop or Sleep mode, however this might result in a higher

of a LIN wake-up from Stop and Sleep mode. To avoid this conditions its recommended to prior set Active
mode before changing to Stop or Sleep mode.
