24.1 LCD Panel Signal Multiplexing Details

The LCDVD bus has three operating modes. These modes correspond to:
• 4-bit Mono STN single panel
• 4-bit Mono STN dual panel
• 8-bit Mono STN single panel
Table 24-1 shows which LCDVD pins are used to supply the pixel data to the panel for
each of the above modes of operation. Table 24-2 shows all of the muxing possibilities for
each LCD Driver pin.
