During SBC Sleep Mode (see
regulator switched-off. As the microcontroller cannot be supplied, the integrated window watchdog can be disabled
in Sleep Mode via a dedicated SPI control bit. However, it can be turned-on for periodically waking-up the system,
e.g. ECU, by generating a reset and automatically switching to SBC Standby Mode.
This mode is entered via SPI command, and turns-off the integrated LIN bus transceiver, main voltage regulator
as well as all switches. Upon a voltage level change at the monitoring / wake-up pins or by LIN message the SBC
Sleep Mode will be terminated and the SBC Standby Mode will automatically be entered (turning-on the LDO).
Note: Upon a wake-up via LIN message the (internal) RxD signal stays “low” until mode switch.
Note: If the Window Watchdog was not enabled in Sleep Mode the Window Watchdog starts after wake-up with a
