| 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. |
