bogdanm 0:9b334a45a8ff 20 [..]
bogdanm 0:9b334a45a8ff 21 (+) Enable the RTC domain access.
bogdanm 0:9b334a45a8ff 22 (+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
bogdanm 0:9b334a45a8ff 23 format using the HAL_RTC_Init() function.

bogdanm 0:9b334a45a8ff 27 [..]
bogdanm 0:9b334a45a8ff 28 (+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTCEx_SetWakeUpTimer()
bogdanm 0:9b334a45a8ff 29 function. You can also configure the RTC Wakeup timer with interrupt mode
bogdanm 0:9b334a45a8ff 30 using the HAL_RTCEx_SetWakeUpTimer_IT() function.
bogdanm 0:9b334a45a8ff 31 (+) To read the RTC WakeUp Counter register, use the HAL_RTCEx_GetWakeUpTimer()
bogdanm 0:9b334a45a8ff 32 function.

bogdanm 0:9b334a45a8ff 40 interrupt mode using the HAL_RTCEx_SetTimeStamp_IT() function.
bogdanm 0:9b334a45a8ff 41 (+) To read the RTC TimeStamp Time and Date register, use the HAL_RTCEx_GetTimeStamp()
bogdanm 0:9b334a45a8ff 42 function.

bogdanm 0:9b334a45a8ff 57 function.
bogdanm 0:9b334a45a8ff 58 (+) To read the RTC Backup Data registers, use the HAL_RTCEx_BKUPRead()
