.. tabs::

   .. group-tab:: Node specific properties

      Properties not inherited from the base binding file.

      .. list-table::
         :widths: 1 1 4
         :header-rows: 1

         * - Name
           - Type
           - Details

         * - ``center-aligned``
           - ``boolean``
           - .. code-block:: none

                Set this to use center-aligned (up and down) counter mode.


         * - ``ch0-pin``
           - ``int``
           - .. code-block:: none

                The channel 0 pin to use.

                For pins P0.0 through P0.31, use the pin number. For example,
                to use P0.16 for channel 0, set:

                    ch0-pin = <16>;

                For pins P1.0 through P1.31, add 32 to the pin number. For
                example, to use P1.2 for channel 0, set:

                    ch0-pin = <34>;  /* 32 + 2 */



         * - ``ch0-inverted``

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

                as the ch0-pin property's.

           - ``boolean``
           - .. code-block:: 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
