| description: |
| The LCD Controller (LCDC) consists of logic for transferring LCD image |
| data from an external display buffer to a TFT LCD panel. The LCDC has one |
| display input buffer per layer that fetches pixels through the single bus |
| host interface and a look-up table to allow palletized display |
| configurations. |
