phungductung	0:e87aa4c49e95	17	==============================================================================
phungductung	0:e87aa4c49e95	18	##### How to use this driver #####
phungductung	0:e87aa4c49e95	19	==============================================================================
phungductung	0:e87aa4c49e95	20	[..]
phungductung	0:e87aa4c49e95	21	(+) Enable the RTC domain access.
phungductung	0:e87aa4c49e95	22	(+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
phungductung	0:e87aa4c49e95	23	format using the HAL_RTC_Init() function.
phungductung	0:e87aa4c49e95	24
phungductung	0:e87aa4c49e95	25	* RTC Wakeup configuration *
phungductung	0:e87aa4c49e95	26	================================
phungductung	0:e87aa4c49e95	27	[..]
phungductung	0:e87aa4c49e95	28	(+) To configure the RTC Wakeup Clock source and Counter use the HAL_RTC_SetWakeUpTimer()
phungductung	0:e87aa4c49e95	29	function. You can also configure the RTC Wakeup timer in interrupt mode
phungductung	0:e87aa4c49e95	30	using the HAL_RTC_SetWakeUpTimer_IT() function.
phungductung	0:e87aa4c49e95	31	(+) To read the RTC WakeUp Counter register, use the HAL_RTC_GetWakeUpTimer()
phungductung	0:e87aa4c49e95	32	function.
phungductung	0:e87aa4c49e95	33
phungductung	0:e87aa4c49e95	34	* TimeStamp configuration *
phungductung	0:e87aa4c49e95	35	===============================
phungductung	0:e87aa4c49e95	36	[..]
phungductung	0:e87aa4c49e95	37	(+) Enables the RTC TimeStamp using the HAL_RTC_SetTimeStamp() function.
phungductung	0:e87aa4c49e95	38	You can also configure the RTC TimeStamp with interrupt mode using the
phungductung	0:e87aa4c49e95	39	HAL_RTC_SetTimeStamp_IT() function.
phungductung	0:e87aa4c49e95	40	(+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp()
phungductung	0:e87aa4c49e95	41	function.
phungductung	0:e87aa4c49e95	42
phungductung	0:e87aa4c49e95	43	* Internal TimeStamp configuration *
phungductung	0:e87aa4c49e95	44	===============================
phungductung	0:e87aa4c49e95	45	[..]
phungductung	0:e87aa4c49e95	46	(+) Enables the RTC internal TimeStamp using the HAL_RTC_SetInternalTimeStamp() function.
phungductung	0:e87aa4c49e95	47	(+) To read the RTC TimeStamp Time and Date register, use the HAL_RTC_GetTimeStamp()
phungductung	0:e87aa4c49e95	48	function.
phungductung	0:e87aa4c49e95	49
phungductung	0:e87aa4c49e95	50	* Tamper configuration *
phungductung	0:e87aa4c49e95	51	============================
phungductung	0:e87aa4c49e95	52	[..]
phungductung	0:e87aa4c49e95	53	(+) Enable the RTC Tamper and Configure the Tamper filter count, trigger Edge
phungductung	0:e87aa4c49e95	54	or Level according to the Tamper filter (if equal to 0 Edge else Level)
phungductung	0:e87aa4c49e95	55	value, sampling frequency, NoErase, MaskFlag, precharge or discharge and
phungductung	0:e87aa4c49e95	56	Pull-UP using the HAL_RTC_SetTamper() function. You can configure RTC Tamper
phungductung	0:e87aa4c49e95	57	with interrupt mode using HAL_RTC_SetTamper_IT() function.
phungductung	0:e87aa4c49e95	58	(+) The default configuration of the Tamper erases the backup registers. To avoid
phungductung	0:e87aa4c49e95	59	erase, enable the NoErase field on the RTC_TAMPCR register.
phungductung	0:e87aa4c49e95	60
phungductung	0:e87aa4c49e95	61	* Backup Data Registers configuration *
phungductung	0:e87aa4c49e95	62	===========================================
phungductung	0:e87aa4c49e95	63	[..]
phungductung	0:e87aa4c49e95	64	(+) To write to the RTC Backup Data registers, use the HAL_RTC_BKUPWrite()
phungductung	0:e87aa4c49e95	65	function.
phungductung	0:e87aa4c49e95	66	(+) To read the RTC Backup Data registers, use the HAL_RTC_BKUPRead()
