The LCD controller consists of two independent controllers, the Raster Controller and the LCD Interface Display Driver (LIDD) controller. Each controller operates independently from the other and only one of them is active at any given time.
Figure 20-1 shows the LCD controller details. The raster and LIDD controllers are responsible for generating the correct external timing. The LCD DMA engine provides a constant flow of data from the frame buffers to the external LCD panel through the Raster and LIDD controllers. In addition, CPU access is provided to read and write registers.
Figure 20-1 shows the LCD block diagram. For more information on the Raster controller data path, see Figure 20-3.
