|
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.
