*Generate LFCLK by on-chip Crystal Oscillator*

Type: ``bool``

Help
====

.. code-block:: none

    When this option is enabled, the internal 32.768 KHz clock (LFCLK)
    is generated by the on-chip Crystal Oscillator (XTOSC).
    This includes an on-chip oscillator, to which an external crystal
    and the related passive components are connected.

Direct dependencies
===================

\ :kconfig:`CLOCK_CONTROL_NPCX <CONFIG_CLOCK_CONTROL_NPCX>` && \ :kconfig:`CLOCK_CONTROL <CONFIG_CLOCK_CONTROL>`

*(Includes any dependencies from ifs and menus.)*

Defaults
