uint32_t HAL_RTCEx_BKUPRead	(	RTC_HandleTypeDef *	hrtc,
		uint32_t	BackupRegister
	)

Reads data from the specified RTC Backup data Register.

Parameters:

hrtc,:	pointer to a RTC_HandleTypeDef structure that contains the configuration information for RTC.
BackupRegister,:	RTC Backup data Register number. This parameter can be: RTC_BKP_DRx where x can be from 1 to 10 (or 42) to specify the register (depending devices).

Return values:

Read

void HAL_RTCEx_BKUPWrite	(	RTC_HandleTypeDef *	hrtc,
		uint32_t	BackupRegister,
		uint32_t	Data
	)

Writes a data in a specified RTC Backup data register.

Parameters:

hrtc,:	pointer to a RTC_HandleTypeDef structure that contains the configuration information for RTC.
BackupRegister,:	RTC Backup data Register number. This parameter can be: RTC_BKP_DRx where x can be from 1 to 10 (or 42) to specify the register (depending devices).
Data,:	Data to be written in the specified RTC Backup data register.

Return values:

None

HAL_StatusTypeDef HAL_RTCEx_SetSmoothCalib	(	RTC_HandleTypeDef *	hrtc,
		uint32_t	SmoothCalibPeriod,
		uint32_t	SmoothCalibPlusPulses,
		uint32_t	SmouthCalibMinusPulsesValue
	)

Sets the Smooth calibration parameters.

Parameters:

hrtc,:	RTC handle
SmoothCalibPeriod,:	Not used (only present for compatibility with another families)
SmoothCalibPlusPulses,:	Not used (only present for compatibility with another families)
SmouthCalibMinusPulsesValue,:	specifies the RTC Clock Calibration value. This parameter must be a number between 0 and 0x7F.

Return values:
