| void RTC_CalibOutputConfig | ( | uint32_t | RTC_CalibOutput ) |
Configures 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_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 calibration 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
