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	* Outputs configuration *
bogdanm	0:9b334a45a8ff	35	=============================
bogdanm	0:9b334a45a8ff	36	[..] The RTC has 2 different outputs:
bogdanm	0:9b334a45a8ff	37	(+) RTC_ALARM: this output is used to manage the RTC Alarm A, Alarm B
bogdanm	0:9b334a45a8ff	38	and WaKeUp signals.
bogdanm	0:9b334a45a8ff	39	To output the selected RTC signal, use the HAL_RTC_Init() function.
bogdanm	0:9b334a45a8ff	40	(+) RTC_CALIB: this output is 512Hz signal or 1Hz.
bogdanm	0:9b334a45a8ff	41	To enable the RTC_CALIB, use the HAL_RTCEx_SetCalibrationOutPut() function.
bogdanm	0:9b334a45a8ff	42	(+) Two pins can be used as RTC_ALARM or RTC_CALIB (PC13, PB2) managed on
bogdanm	0:9b334a45a8ff	43	the RTC_OR register.
bogdanm	0:9b334a45a8ff	44	(+) When the RTC_CALIB or RTC_ALARM output is selected, the RTC_OUT pin is
bogdanm	0:9b334a45a8ff	45	automatically configured in output alternate function.
bogdanm	0:9b334a45a8ff	46
bogdanm	0:9b334a45a8ff	47	* Smooth digital Calibration configuration *
bogdanm	0:9b334a45a8ff	48	================================================
bogdanm	0:9b334a45a8ff	49	[..]
bogdanm	0:9b334a45a8ff	50	(+) Configure the RTC Original Digital Calibration Value and the corresponding
bogdanm	0:9b334a45a8ff	51	calibration cycle period (32s,16s and 8s) using the HAL_RTCEx_SetSmoothCalib()
bogdanm	0:9b334a45a8ff	52	function.
bogdanm	0:9b334a45a8ff	53
bogdanm	0:9b334a45a8ff	54	* TimeStamp configuration *
bogdanm	0:9b334a45a8ff	55	===============================
bogdanm	0:9b334a45a8ff	56	[..]
bogdanm	0:9b334a45a8ff	57	(+) Enable the RTC TimeStamp using the HAL_RTCEx_SetTimeStamp() function.
bogdanm	0:9b334a45a8ff	58	You can also configure the RTC TimeStamp with interrupt mode using the
bogdanm	0:9b334a45a8ff	59	HAL_RTCEx_SetTimeStamp_IT() function.
bogdanm	0:9b334a45a8ff	60	(+) To read the RTC TimeStamp Time and Date register, use the HAL_RTCEx_GetTimeStamp()
bogdanm	0:9b334a45a8ff	61	function.
bogdanm	0:9b334a45a8ff	62
bogdanm	0:9b334a45a8ff	63	* Internal TimeStamp configuration *
bogdanm	0:9b334a45a8ff	64	===============================
bogdanm	0:9b334a45a8ff	65	[..]
bogdanm	0:9b334a45a8ff	66	(+) Enable the RTC internal TimeStamp using the HAL_RTCEx_SetInternalTimeStamp() function.
bogdanm	0:9b334a45a8ff	67	User has to check internal timestamp occurrence using __HAL_RTC_INTERNAL_TIMESTAMP_GET_FLAG.
bogdanm	0:9b334a45a8ff	68	(+) To read the RTC TimeStamp Time and Date register, use the HAL_RTCEx_GetTimeStamp()
bogdanm	0:9b334a45a8ff	69	function.
bogdanm	0:9b334a45a8ff	70
bogdanm	0:9b334a45a8ff	71	* Tamper configuration *
bogdanm	0:9b334a45a8ff	72	============================
bogdanm	0:9b334a45a8ff	73	[..]
bogdanm	0:9b334a45a8ff	74	(+) Enable the RTC Tamper and configure the Tamper filter count, trigger Edge
bogdanm	0:9b334a45a8ff	75	or Level according to the Tamper filter (if equal to 0 Edge else Level)
bogdanm	0:9b334a45a8ff	76	value, sampling frequency, NoErase, MaskFlag, precharge or discharge and
bogdanm	0:9b334a45a8ff	77	Pull-UP using the HAL_RTCEx_SetTamper() function. You can configure RTC Tamper
bogdanm	0:9b334a45a8ff	78	with interrupt mode using HAL_RTCEx_SetTamper_IT() function.
bogdanm	0:9b334a45a8ff	79	(+) The default configuration of the Tamper erases the backup registers. To avoid
bogdanm	0:9b334a45a8ff	80	erase, enable the NoErase field on the RTC_TAMPCR register.
bogdanm	0:9b334a45a8ff	81
bogdanm	0:9b334a45a8ff	82	* Backup Data Registers configuration *
bogdanm	0:9b334a45a8ff	83	===========================================
bogdanm	0:9b334a45a8ff	84	[..]
bogdanm	0:9b334a45a8ff	85	(+) To write to the RTC Backup Data registers, use the HAL_RTCEx_BKUPWrite()
bogdanm	0:9b334a45a8ff	86	function.
bogdanm	0:9b334a45a8ff	87	(+) To read the RTC Backup Data registers, use the HAL_RTCEx_BKUPRead()
bogdanm	0:9b334a45a8ff	88	function.
