To wake up from the Stop mode with an RTC alarm event, it is necessary to
configure the RTC to generate the RTC alarm using the
HAL_RTC_SetAlarm_IT() function.
To wake up from the Stop mode with an RTC Tamper or time stamp event, it is
necessary to configure the RTC to detect the tamper or time stamp event using
the HAL_RTCEx_SetTimeStamp_IT() or HAL_RTCEx_SetTamper_IT() functions.
To wake up from the Stop mode with an RTC Wake-up event, it is necessary to
configure the RTC to generate the RTC Wake-up event using the
HAL_RTCEx_SetWakeUpTimer_IT() function.
