void RTC_CalibOutputCmd ( FunctionalState NewState )

Enables or disables the RTC clock to be output through the relative pin.

Parameters

NewState,: new state of the digital calibration Output. This parameter can be: ENABLE or DISABLE.

Return values

None

void RTC_CalibOutputConfig ( uint32_t RTC_CalibOutput )

Configure the Calibration Pinout (RTC_CALIB) Selection (1Hz or 512Hz).

Parameters

RTC_CalibOutput

: Select the Calibration output Selection . This parameter can be one of the following values:

RTC_CalibOutput_512Hz: A signal has a regular waveform at 512Hz.
RTC_CalibOutput_1Hz : A signal has a regular waveform at 1Hz.

Return values

None

ErrorStatus RTC_CoarseCalibCmd ( FunctionalState NewState )

Enables or disables the Coarse calibration process.

Parameters

NewState,: new state of the Coarse calibration. This parameter can be: ENABLE or DISABLE.

Return values

An	ErrorStatus enumeration value: SUCCESS: RTC Coarse calibration are enabled/disabled ERROR: RTC Coarse calibration are not enabled/disabled

ErrorStatus RTC_CoarseCalibConfig	(	uint32_t	RTC_CalibSign,
		uint32_t	Value
	)

Configures the Coarse calibration parameters.

Parameters

RTC_CalibSign,:	specifies the sign of the coarse calibration value. This parameter can be one of the following values: RTC_CalibSign_Positive: The value sign is positive RTC_CalibSign_Negative: The value sign is negative
Value,:	value of coarse calibration expressed in ppm (coded on 5 bits).

Note: This Calibration value should be between 0 and 63 when using negative sign with a 2-ppm step.; This Calibration value should be between 0 and 126 when using positive sign with a 4-ppm step.

Return values

An	ErrorStatus enumeration value: SUCCESS: RTC Coarse calibration are initialized ERROR: RTC Coarse calibration are not initialized

ErrorStatus RTC_SmoothCalibConfig	(	uint32_t	RTC_SmoothCalibPeriod,
		uint32_t	RTC_SmoothCalibPlusPulses,
		uint32_t	RTC_SmouthCalibMinusPulsesValue
	)

Configures the Smooth Calibration Settings.

Parameters

RTC_SmoothCalibPeriod	: Select the Smooth Calibration Period. This parameter can be can be one of the following values: RTC_SmoothCalibPeriod_32sec : The smooth calibration periode is 32s. RTC_SmoothCalibPeriod_16sec : The smooth calibration periode is 16s. RTC_SmoothCalibPeriod_8sec : The smooth calibartion periode is 8s.
RTC_SmoothCalibPlusPulses	: Select to Set or reset the CALP bit. This parameter can be one of the following values: RTC_SmoothCalibPlusPulses_Set : Add one RTCCLK puls every 2**11 pulses. RTC_SmoothCalibPlusPulses_Reset: No RTCCLK pulses are added.
RTC_SmouthCalibMinusPulsesValue,:	Select the value of CALM[8:0] bits. This parameter can be one any value from 0 to 0x000001FF.

Return values

An	ErrorStatus enumeration value: SUCCESS: RTC Calib registers are configured ERROR: RTC Calib registers are not configured
