bogdanm	0:9b334a45a8ff	7	* @brief RTC HAL module driver.
bogdanm	0:9b334a45a8ff	8	* This file provides firmware functions to manage the following
bogdanm	0:9b334a45a8ff	9	* functionalities of the Real Time Clock (RTC) Extension peripheral:
bogdanm	0:9b334a45a8ff	10	* + RTC Time Stamp functions
bogdanm	0:9b334a45a8ff	11	* + RTC Tamper functions

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 Wake-up configuration *
bogdanm	0:9b334a45a8ff	26	================================
bogdanm	0:9b334a45a8ff	27	[..]
bogdanm	0:9b334a45a8ff	28	(+) To configure the RTC Wake-up Clock source and Counter use the HAL_RTC_SetWakeUpTimer()
bogdanm	0:9b334a45a8ff	29	function. You can also configure the RTC Wake-up timer in interrupt mode
bogdanm	0:9b334a45a8ff	30	using the HAL_RTC_SetWakeUpTimer_IT() function.
bogdanm	0:9b334a45a8ff	31	(+) To read the RTC Wake-up 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	(+) Configure the RTC_AFx trigger and enable the RTC TimeStamp using the
bogdanm	0:9b334a45a8ff	38	HAL_RTC_SetTimeStamp() function. You can also configure the RTC TimeStamp with
bogdanm	0:9b334a45a8ff	39	interrupt mode using the 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	(+) The TIMESTAMP alternate function can be mapped either to RTC_AF1 (PC13)
bogdanm	0:9b334a45a8ff	43	or RTC_AF2 (PI8 or PA0 only for STM32F446xx devices) depending on the value of TSINSEL bit in
bogdanm	0:9b334a45a8ff	44	RTC_TAFCR register. The corresponding pin is also selected by HAL_RTC_SetTimeStamp()
bogdanm	0:9b334a45a8ff	45	or HAL_RTC_SetTimeStamp_IT() function.
bogdanm	0:9b334a45a8ff	46
bogdanm	0:9b334a45a8ff	47	* Tamper configuration *
bogdanm	0:9b334a45a8ff	48	============================
bogdanm	0:9b334a45a8ff	49	[..]
bogdanm	0:9b334a45a8ff	50	(+) Enable the RTC Tamper and configure the Tamper filter count, trigger Edge
bogdanm	0:9b334a45a8ff	51	or Level according to the Tamper filter (if equal to 0 Edge else Level)
bogdanm	0:9b334a45a8ff	52	value, sampling frequency, precharge or discharge and Pull-UP using the
bogdanm	0:9b334a45a8ff	53	HAL_RTC_SetTamper() function. You can configure RTC Tamper in interrupt
bogdanm	0:9b334a45a8ff	54	mode using HAL_RTC_SetTamper_IT() function.
bogdanm	0:9b334a45a8ff	55	(+) The TAMPER1 alternate function can be mapped either to RTC_AF1 (PC13)
bogdanm	0:9b334a45a8ff	56	or RTC_AF2 (PI8 or PA0 only for STM32F446xx devices) depending on the value of TAMP1INSEL bit in
bogdanm	0:9b334a45a8ff	57	RTC_TAFCR register. The corresponding pin is also selected by HAL_RTC_SetTamper()
bogdanm	0:9b334a45a8ff	58	or HAL_RTC_SetTamper_IT() function.
bogdanm	0:9b334a45a8ff	59
bogdanm	0:9b334a45a8ff	60	* Backup Data Registers configuration *
bogdanm	0:9b334a45a8ff	61	===========================================
bogdanm	0:9b334a45a8ff	62	[..]
bogdanm	0:9b334a45a8ff	63	(+) To write to the RTC Backup Data registers, use the HAL_RTC_BKUPWrite()
bogdanm	0:9b334a45a8ff	64	function.
bogdanm	0:9b334a45a8ff	65	(+) To read the RTC Backup Data registers, use the HAL_RTC_BKUPRead()
bogdanm	0:9b334a45a8ff	66	function.
