.. code-block:: none

   Software loopback Pulse IO controller. A functional backend that loops
   transmitted symbols back on receive, for testing the subsystem API
   without hardware.

           - ``int``
           - .. code-block:: none

                Number of cells in a pulse-ios specifier. Must be 1; the single
                cell selects the channel index on the controller.



             This property is **required**.

             Constant value: ``1``



   .. group-tab:: Deprecated node specific properties

      Deprecated properties not inherited from the base binding file.

      (None)

   .. group-tab:: Base properties

      Properties inherited from the base binding file, which defines
      common properties that may be set on many nodes. Not all of these
      may apply to the "zephyr,pulse-io-loopback" compatible.

      (None)
