... Then the watchdog again starts by opening a long open window. In addition, a “window watchdog reset flag” is set within the SPI to monitor a watchdog reset. For fail safe reasons the TLE7824G is automatically switched to SBC Standby mode if a watchdog trigger failure occurs. This minimizes the power consumption in case of a permanent faulty microcontroller. This “ ...

... In addition to a wake-up from SBC Stop / Sleep Mode via the LIN bus line it is also possible to wake-up the TLE7824G from low power mode via the monitoring/wake-up inputs. These inputs are sensitive to a transition of the voltage level, either from high to low or vice versa. Monitoring is available in Active Mode and indicates the voltage level of the inputs via SPI status bits ...
