29 / 100 page  Data Sheet 29 Rev. 1.02 2018-02-02 TLE9255W Modes of Operation 5.8 RxD pin wake-up behavior The RxD output pin indicates a wake-up event to the microcontroller. On detection of a valid wake-up event the RxD output pin reacts with one of the following behaviors, depending on the WAKE_TOG bit in the SPI register HW_CTRL: • RxD output pin is set to “low” • RxD output pin starts to toggle If Stand-by Mode is re-entered by a mode change (microcontroller) the previous indication of a valid wake-up event is not signalled on the RxD pin. Only if a new wake-up event has been detected, the RxD pin indicates the wake-up event. The clearing of a WUP, WUF or LWU has no influence on the behavior of the RxD pin. 5.8.1 RxD permanent “low” If a valid wake-up event is detected AND if SPI bit WAKE_TOG = 0, then the RxD output pin is set to “low”. If a mode change occurs, then the RxD output pin behavior is defined by the new state. Figure 20 RxD “low” after wake-up event Figure 21 RxD “low” after wake-up event (permanently supplied VIO) wake-up event detected Sleep Mode Stand-by Mode Mode RxD RxD remains permanently logical „low“ t tMode_Change t Stand-by Mode tMode_Change 30% VIO Mode RxD RxD remains permanently logical „low“ Sleep Mode wake-up event detected |
