The LCD controller has the option to use the internal SRAM or external memory through the EPI interface to hold the frame buffer. The frame buffer is a contiguous memory block, storing enough data to fill a full LCD screen. The frame buffer contains the palette look-up table (palette RAM) and the frame data for a given source image. When moving data into the LCD, the PALMODE bit in the LCD Raster Control (LCDRASTRCTL) register can be configured for palette and data loading, palette loading only or data loading only.
NOTE
When using the LCD with EPI to interface to external memory, the external code address space 0x1000.0000 must be selected by programing the ECADR field to 0x1 in the EPI Address Map (EPIADDRMAP) register at EPI offset 0x01C.
