.. title:: CLOCK_CONTROL_NRF_K32SRC_RC_CALIBRATION

.. option:: CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC_CALIBRATION

*Enable LF clock calibration*

Type: ``bool``

Help
====

If calibration is disabled when RC is used for low frequency clock then
accuracy of the low frequency clock will degrade. Disable on your own
risk.
