*Internal high frequency RC oscillator frequency*

*Internal high frequency RC oscillator frequency*

Type: ``int``

Help
====

.. code-block:: none

    Set the internal high frequency RC oscillator frequency in Hz. This should be set by the
    board's defconfig. Only supported values may be used here. Setting this to 0, skips the
    configuration of the high frequency RC oscillator completely. This may be desired, if
    the bootloader already configured it properly or the device's default clock source should
    be used with it's default configuration.
