Functions
ErrorStatus	LL_RTC_DeInit (RTC_TypeDef *RTCx)
	De-Initializes the RTC registers to their default reset values.
ErrorStatus	LL_RTC_Init (RTC_TypeDef *RTCx, LL_RTC_InitTypeDef *RTC_InitStruct)
	Initializes the RTC registers according to the specified parameters in RTC_InitStruct.
void	LL_RTC_StructInit (LL_RTC_InitTypeDef *RTC_InitStruct)
	Set each LL_RTC_InitTypeDef field to default value.
ErrorStatus	LL_RTC_TIME_Init (RTC_TypeDef *RTCx, uint32_t RTC_Format, LL_RTC_TimeTypeDef *RTC_TimeStruct)
	Set the RTC current time.
void	LL_RTC_TIME_StructInit (LL_RTC_TimeTypeDef *RTC_TimeStruct)
	Set each LL_RTC_TimeTypeDef field to default value (Time = 00h:00min:00sec).
ErrorStatus	LL_RTC_DATE_Init (RTC_TypeDef *RTCx, uint32_t RTC_Format, LL_RTC_DateTypeDef *RTC_DateStruct)
	Set the RTC current date.
void	LL_RTC_DATE_StructInit (LL_RTC_DateTypeDef *RTC_DateStruct)
	Set each LL_RTC_DateTypeDef field to default value (date = Monday, January 01 xx00)
ErrorStatus	LL_RTC_ALMA_Init (RTC_TypeDef *RTCx, uint32_t RTC_Format, LL_RTC_AlarmTypeDef *RTC_AlarmStruct)
	Set the RTC Alarm A.

void	LL_RTC_ALMA_StructInit (LL_RTC_AlarmTypeDef *RTC_AlarmStruct)
	Set each LL_RTC_AlarmTypeDef of ALARMA field to default value (Time = 00h:00mn:00sec / Day = 1st day of the month/Mask = all fields are masked).
void	LL_RTC_ALMB_StructInit (LL_RTC_AlarmTypeDef *RTC_AlarmStruct)
	Set each LL_RTC_AlarmTypeDef of ALARMA field to default value (Time = 00h:00mn:00sec / Day = 1st day of the month/Mask = all fields are masked).
ErrorStatus	LL_RTC_EnterInitMode (RTC_TypeDef *RTCx)
	Enters the RTC Initialization mode.
ErrorStatus	LL_RTC_ExitInitMode (RTC_TypeDef *RTCx)
	Exit the RTC Initialization mode.
ErrorStatus	LL_RTC_WaitForSynchro (RTC_TypeDef *RTCx)
	Waits until the RTC Time and Day registers (RTC_TR and RTC_DR) are synchronized with RTC APB clock.
