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_RTC_SetWakeUpTimer()
bogdanm	0:9b334a45a8ff	29	function. You can also configure the RTC Wakeup timer in interrupt mode
bogdanm	0:9b334a45a8ff	30	using the HAL_RTC_SetWakeUpTimer_IT() function.
bogdanm	0:9b334a45a8ff	31	(+) To read the RTC WakeUp Counter register, use the HAL_RTC_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	(+) Enables the RTC TimeStamp using the HAL_RTC_SetTimeStamp() function.
bogdanm	0:9b334a45a8ff	38	You can also configure the RTC TimeStamp with interrupt mode using the
bogdanm	0:9b334a45a8ff	39	HAL_RTC_SetTimeStamp_IT() function.
bogdanm	0:9b334a45a8ff	40	(+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp()
bogdanm	0:9b334a45a8ff	41	function.
bogdanm	0:9b334a45a8ff	42
bogdanm	0:9b334a45a8ff	43	* Internal TimeStamp configuration *
bogdanm	0:9b334a45a8ff	44	===============================
bogdanm	0:9b334a45a8ff	45	[..]
bogdanm	0:9b334a45a8ff	46	(+) Enables the RTC internal TimeStamp using the HAL_RTC_SetInternalTimeStamp() function.
bogdanm	0:9b334a45a8ff	47	(+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp()
bogdanm	0:9b334a45a8ff	48	function.
bogdanm	0:9b334a45a8ff	49
bogdanm	0:9b334a45a8ff	50	* Tamper configuration *
bogdanm	0:9b334a45a8ff	51	============================
bogdanm	0:9b334a45a8ff	52	[..]
bogdanm	0:9b334a45a8ff	53	(+) Enable the RTC Tamper and Configure the Tamper filter count, trigger Edge
bogdanm	0:9b334a45a8ff	54	or Level according to the Tamper filter (if equal to 0 Edge else Level)
bogdanm	0:9b334a45a8ff	55	value, sampling frequency, NoErase, MaskFlag, precharge or discharge and
bogdanm	0:9b334a45a8ff	56	Pull-UP using the HAL_RTC_SetTamper() function. You can configure RTC Tamper
bogdanm	0:9b334a45a8ff	57	with interrupt mode using HAL_RTC_SetTamper_IT() function.
bogdanm	0:9b334a45a8ff	58	(+) The default configuration of the Tamper erases the backup registers. To avoid
bogdanm	0:9b334a45a8ff	59	erase, enable the NoErase field on the RTC_TAMPCR register.
bogdanm	0:9b334a45a8ff	60
bogdanm	0:9b334a45a8ff	61	* Backup Data Registers configuration *
bogdanm	0:9b334a45a8ff	62	===========================================
bogdanm	0:9b334a45a8ff	63	[..]
bogdanm	0:9b334a45a8ff	64	(+) To write to the RTC Backup Data registers, use the HAL_RTC_BKUPWrite()
bogdanm	0:9b334a45a8ff	65	function.
bogdanm	0:9b334a45a8ff	66	(+) To read the RTC Backup Data registers, use the HAL_RTC_BKUPRead()
bogdanm	0:9b334a45a8ff	67	function.
