- /**@brief Waits for an application event.
- *
- * An application event is either an application interrupt or a pended interrupt when the
- * interrupt is disabled. When the interrupt is enabled it will be taken immediately since
- * this function will wait in thread mode, then the execution will return in the application's
- * main thread. When an interrupt is disabled and gets pended it will return to the application's
- * thread main. The application must ensure that the pended flag is cleared using
- * ::sd_nvic_ClearPendingIRQ in order to sleep using this function. This is only necessary for
- * disabled interrupts, as the interrupt handler will clear the pending flag automatically for
- * enabled interrupts.
- *
- * In order to wake up from disabled interrupts, the SEVONPEND flag has to be set in the Cortex-M0
- * System Control Register (SCR). @sa CMSIS_SCB
- *
- * @note If an application interrupt has happened since the last time sd_app_evt_wait was
- * called this function will return immediately and not go to sleep. This is to avoid race
- * conditions that can occur when a flag is updated in the interrupt handler and processed
- * in the main loop.
- *
- * @post An application interrupt has happened or a interrupt pending flag is set.
- *
- * @retval ::NRF_SUCCESS
