bogdanm	0:9b334a45a8ff	17	==============================================================================
bogdanm	0:9b334a45a8ff	18	##### How to use this driver #####
bogdanm	0:9b334a45a8ff	19	==============================================================================
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	24
bogdanm	0:9b334a45a8ff	25	* RTC Wakeup configuration *
bogdanm	0:9b334a45a8ff	26	================================
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	33
bogdanm	0:9b334a45a8ff	34	* TimeStamp configuration *
bogdanm	0:9b334a45a8ff	35	===============================
bogdanm	0:9b334a45a8ff	36	[..]
bogdanm	0:9b334a45a8ff	37	(+) Configure the RTC_AFx trigger and enables the RTC TimeStamp using the
bogdanm	0:9b334a45a8ff	38	HAL_RTCEx_SetTimeStamp() function. You can also configure the RTC TimeStamp with
bogdanm	0:9b334a45a8ff	39	interrupt mode using the HAL_RTCEx_SetTimeStamp_IT() function.
bogdanm	0:9b334a45a8ff	40	(+) To read the RTC TimeStamp Time and Date register, use the HAL_RTCEx_GetTimeStamp()
bogdanm	0:9b334a45a8ff	41	function.
bogdanm	0:9b334a45a8ff	42	(+) The TIMESTAMP alternate function is mapped to RTC_AF1 (PC13).
bogdanm	0:9b334a45a8ff	43
bogdanm	0:9b334a45a8ff	44	* Tamper configuration *
bogdanm	0:9b334a45a8ff	45	============================
bogdanm	0:9b334a45a8ff	46	[..]
bogdanm	0:9b334a45a8ff	47	(+) Enable the RTC Tamper and Configure the Tamper filter count, trigger Edge
bogdanm	0:9b334a45a8ff	48	or Level according to the Tamper filter (if equal to 0 Edge else Level)
bogdanm	0:9b334a45a8ff	49	value, sampling frequency, precharge or discharge and Pull-UP using the
bogdanm	0:9b334a45a8ff	50	HAL_RTCEx_SetTamper() function. You can configure RTC Tamper with interrupt
bogdanm	0:9b334a45a8ff	51	mode using HAL_RTCEx_SetTamper_IT() function.
bogdanm	0:9b334a45a8ff	52	(+) The TAMPER1 alternate function is mapped to RTC_AF1 (PC13).
bogdanm	0:9b334a45a8ff	53
bogdanm	0:9b334a45a8ff	54	* Backup Data Registers configuration *
bogdanm	0:9b334a45a8ff	55	===========================================
bogdanm	0:9b334a45a8ff	56	[..]
bogdanm	0:9b334a45a8ff	57	(+) To write to the RTC Backup Data registers, use the HAL_RTCEx_BKUPWrite()
bogdanm	0:9b334a45a8ff	58	function.
bogdanm	0:9b334a45a8ff	59	(+) To read the RTC Backup Data registers, use the HAL_RTCEx_BKUPRead()
bogdanm	0:9b334a45a8ff	60	function.
