CONFIG_CLOCK_CONTROL_NRF_CALIBRATION_PERIOD

Calibration opportunity period in milliseconds

Type: int

Help

Periodically, calibration action is performed. Action includes
temperature measurement followed by clock calibration. Calibration may
be skipped if temperature change (compared to measurement of previous
calibration) did not exceeded CLOCK_CONTROL_NRF_CALIBRATION_TEMP_DIFF
and number of consecutive skips did not exceeded
CLOCK_CONTROL_NRF_CALIBRATION_MAX_SKIP.
