sahilmgandhi	18:6a4db94011d3	17	==============================================================================
sahilmgandhi	18:6a4db94011d3	18	##### How to use this driver #####
sahilmgandhi	18:6a4db94011d3	19	==============================================================================
sahilmgandhi	18:6a4db94011d3	20	[..]
sahilmgandhi	18:6a4db94011d3	21	(+) Enable the RTC domain access.
sahilmgandhi	18:6a4db94011d3	22	(+) Configure the RTC Prescaler (Asynchronous and Synchronous) and RTC hour
sahilmgandhi	18:6a4db94011d3	23	format using the HAL_RTC_Init() function.
sahilmgandhi	18:6a4db94011d3	24
sahilmgandhi	18:6a4db94011d3	25	* RTC Wake-up configuration *
sahilmgandhi	18:6a4db94011d3	26	================================
sahilmgandhi	18:6a4db94011d3	27	[..]
sahilmgandhi	18:6a4db94011d3	28	(+) To configure the RTC Wake-up Clock source and Counter use the HAL_RTCEx_SetWakeUpTimer()
sahilmgandhi	18:6a4db94011d3	29	function. You can also configure the RTC Wake-up timer in interrupt mode
sahilmgandhi	18:6a4db94011d3	30	using the HAL_RTCEx_SetWakeUpTimer_IT() function.
sahilmgandhi	18:6a4db94011d3	31	(+) To read the RTC Wake-up Counter register, use the HAL_RTCEx_GetWakeUpTimer()
sahilmgandhi	18:6a4db94011d3	32	function.
sahilmgandhi	18:6a4db94011d3	33
sahilmgandhi	18:6a4db94011d3	34	* TimeStamp configuration *
sahilmgandhi	18:6a4db94011d3	35	===============================
sahilmgandhi	18:6a4db94011d3	36	[..]
sahilmgandhi	18:6a4db94011d3	37	(+) Configure the RTC_AFx trigger and enable the RTC TimeStamp using the
sahilmgandhi	18:6a4db94011d3	38	HAL_RTCEx_SetTimeStamp() function. You can also configure the RTC TimeStamp with
sahilmgandhi	18:6a4db94011d3	39	interrupt mode using the HAL_RTCEx_SetTimeStamp_IT() function.
sahilmgandhi	18:6a4db94011d3	40	(+) To read the RTC TimeStamp Time and Date register, use the HAL_RTCEx_GetTimeStamp()
sahilmgandhi	18:6a4db94011d3	41	function.
sahilmgandhi	18:6a4db94011d3	42	(+) The TIMESTAMP alternate function can be mapped either to RTC_AF1 (PC13)
sahilmgandhi	18:6a4db94011d3	43	or RTC_AF2 (PI8) depending on the value of TSINSEL bit in
sahilmgandhi	18:6a4db94011d3	44	RTC_TAFCR register. The corresponding pin is also selected by HAL_RTCEx_SetTimeStamp()
sahilmgandhi	18:6a4db94011d3	45	or HAL_RTCEx_SetTimeStamp_IT() function.
sahilmgandhi	18:6a4db94011d3	46
sahilmgandhi	18:6a4db94011d3	47	* Tamper configuration *
sahilmgandhi	18:6a4db94011d3	48	============================
sahilmgandhi	18:6a4db94011d3	49	[..]
sahilmgandhi	18:6a4db94011d3	50	(+) Enable the RTC Tamper and configure the trigger using the HAL_RTCEx_SetTamper() function.
sahilmgandhi	18:6a4db94011d3	51	You can configure RTC Tamper in interrupt mode using HAL_RTCEx_SetTamper_IT() function.
sahilmgandhi	18:6a4db94011d3	52	(+) The TAMPER1 alternate function can be mapped either to RTC_AF1 (PC13)
sahilmgandhi	18:6a4db94011d3	53	or RTC_AF2 (PI8) depending on the value of TAMP1INSEL bit in
sahilmgandhi	18:6a4db94011d3	54	RTC_TAFCR register. The corresponding pin is also selected by HAL_RTCEx_SetTamper()
sahilmgandhi	18:6a4db94011d3	55	or HAL_RTCEx_SetTamper_IT() function.
sahilmgandhi	18:6a4db94011d3	56
sahilmgandhi	18:6a4db94011d3	57	* Backup Data Registers configuration *
sahilmgandhi	18:6a4db94011d3	58	===========================================
sahilmgandhi	18:6a4db94011d3	59	[..]
sahilmgandhi	18:6a4db94011d3	60	(+) To write to the RTC Backup Data registers, use the HAL_RTCEx_BKUPWrite()
sahilmgandhi	18:6a4db94011d3	61	function.
sahilmgandhi	18:6a4db94011d3	62	(+) To read the RTC Backup Data registers, use the HAL_RTCEx_BKUPRead()
sahilmgandhi	18:6a4db94011d3	63	function.
