It may not be possible to protect the power supply against an unintended power cycle and reset. Therefore, the MCU needs a safe reset logic to ensure that a correct reset always happens. This application note shows typical test scenarios for interruption or disturbance on a car power supply whereby the MCU cannot be powered up from a 0 V level.
