           - Details

         * - ``clock-frequency``
           - ``int``
           - .. code-block:: none

                Counter clock frequency


             This property is **required**.

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

                The frequency of the counter is divided by this value.


             This property is **required**.

         * - ``clk-source``
           - ``int``
           - .. code-block:: none

                Selects the clock to be used by the LPMTR prescaler/glitch filter.
                In time counter mode, this field selects the input clock to the prescaler.
                In pulse counter mode, this field selects the input clock to the glitch filter.
                The clock connections vary by device, see the device reference manual for
                more details.



             This property is **required**.

             Legal values: ``0``, ``1``, ``2``, ``3``

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

                When LPTMR is in Pulse mode, this value
                will be used to determine the "rising-edge
                source pin" to increment the lptmr counter.



         * - ``active-low``
           - ``boolean``
           - .. code-block:: none

                When LPTMR is in Pulse mode, this value
                will set the counter to active low.



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

                Represents the width of the counter in bits.


             This property is **required**.

         * - ``prescale-glitch-filter``
           - ``int``
           - .. code-block:: none

                When in prescaler mode, the counter is incremented every
                  2 ^ [prescaler-glitch-filter] clock cycles.
                When in pulse mode, the counter is incremented every
                  2 ^ [prescaler-glitch-filter] rising edges detected
                  by the pin configured from the input-pin value.
                  Note, that the pulse mode cannot be 2 ^ 16.



             Default value: ``1``

             Legal values: ``1``, ``2``, ``3``, ``4``, ``5``, ``6``, ``7``, ``8``, ``9``, ``10``, ``11``, ``12``, ``13``, ``14``, ``15``, ``16``

         * - ``timer-mode-sel``
           - ``int``
           - .. code-block:: none

                This value determines rather the LPTMR is configured
                for Time-Counter mode or for Pulse mode.
                0 <- LPTMR is configured for Time Counter Mode.
                1 <- LPTMR is configured for Pulse Mode.



             Legal values: ``0``, ``1``
