CONFIG_TIMEOUT_64BIT
####################

*Store kernel timeouts in 64 bit precision*

Type: ``bool``

Help
====

.. code-block:: none

    When this option is true, the k_ticks_t values passed to
    kernel APIs will be a 64 bit quantity, allowing the use of
    larger values (and higher precision tick rates) without fear
    of overflowing the 32 bit word.  This feature also gates the
    availability of absolute timeout values (which require the
    extra precision).

Default
=======

- y
