*CAVS DSP Wall Clock Timer on Intel SoC*

Type: ``bool``

Help
====

.. code-block:: none

    The DSP wall clock timer is a timer driven directly by
    external oscillator and is external to the CPU core(s).
    It is not as fast as the internal core clock, but provides
    a common and synchronized counter for all CPU cores (which
    is useful for SMP).
