Waits for an application event.
An application event is either an application interrupt or a pended interrupt when the interrupt is disabled.
When the application waits for an application event by calling this function, an interrupt that is enabled will be taken immediately on pending since this function will wait in thread mode, then the execution will return in the application's main thread.
In order to wake up from disabled interrupts, the SEVONPEND flag has to be set in the Cortex-M MCU's System Control Register (SCR), CMSIS_SCB. In that case, when a disabled interrupt gets pended, this function will return to the application's main thread.
