      Long Line Mode Enable
      Selects alternate timings for 1-Wire communication.
      The recommended setting depends on the length of the wire.
      For lines less than 40 meters, 0 should be used.

      Setting this bit to 0 leaves the write one release,
      the data sampling, and the time-slot recovery times at
      approximately 5us (micro second), 15us, and 7us, respectively.

      Setting this bit to 1 enables long line mode timings during standard mode communications.
      This mode moves the write one release, the data sampling,
      and the time-slot recovery times out to approximately 8us, 22us, and 14us, respectively.

      0 - Standard operation for lines less than 40 meters.
      1 - Long Line mode enabled.
