   12 description: |
   13   The Kinetic Technologies KTD253 and KTD259 are white LED backlights
   14   controlled by a single GPIO line. If you just turn on the backlight
   15   it goes to maximum backlight then you can set the level of backlight
   16   using pulses on the enable wire. This is sometimes referred to as
   17   "expresswire".
