15
  The LCD Controller (LCDC) consists of logic for transferring LCD image

16
  data from an external display buffer to a TFT LCD panel. The LCDC has one

17
  display input buffer per layer that fetches pixels through the single bus

18
  host interface and a look-up table to allow palletized display

19
  configurations.
