@brief Type representing LFCLK oscillator source.

Fields

source: u8

< LF oscillator clock source, see @ref NRF_CLOCK_LF_SRC.

rc_ctiv: u8

< Only for ::NRF_CLOCK_LF_SRC_RC: Calibration timer interval in 1/4 second units (nRF52: 1-32). @note To avoid excessive clock drift, 0.5 degrees Celsius is the maximum temperature change allowed in one calibration timer interval. The interval should be selected to ensure this.

@note Must be 0 if source is not ::NRF_CLOCK_LF_SRC_RC.

rc_temp_ctiv: u8

< Only for ::NRF_CLOCK_LF_SRC_RC: How often (in number of calibration intervals) the RC oscillator shall be calibrated if the temperature hasn't changed. 0: Always calibrate even if the temperature hasn't changed. 1: Only calibrate if the temperature has changed (legacy - nRF51 only). 2-33: Check the temperature and only calibrate if it has changed, however calibration will take place every rc_temp_ctiv intervals in any case.

@note Must be 0 if source is not ::NRF_CLOCK_LF_SRC_RC.

@note For nRF52, the application must ensure calibration at least once every 8 seconds to ensure +/-500 ppm clock stability. The recommended configuration for ::NRF_CLOCK_LF_SRC_RC on nRF52 is rc_ctiv=16 and rc_temp_ctiv=2. This will ensure calibration at least once every 8 seconds and for temperature changes of 0.5 degrees Celsius every 4 seconds. See the Product Specification for the nRF52 device being used for more information.

accuracy: u8

< External clock accuracy used in the LL to compute timing windows, see @ref NRF_CLOCK_LF_ACCURACY.
