1.2 Frame Buffer

The LCD 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. Operating in RGB Mode requires the LCD frame buffer. The LCD controller has the option to use the internal SRAM memory or external memory through the EPI interface to hold the frame buffer.
