In SNL310, the interface with external 8-bit mode LCD driver is shared with extension

bus. When LCD driver connected to SNL310, chip will allocate a memory area for LCD

driver and the size of this memory area will depend on unit size of each external device.

So it is easy to configure LCD driver and read/write data to/from LCD driver. Figure-13

and Figure-14 show out the system connection of 808/6800 LCD interfaces between

SNL310 and LCD driver.
