2.3 INTERFACE

LCD controller supports 2 types of display device. One type is the conventional RGB-interface that uses RGB
data, Vertical/horizontal sync, data valid signal and data sync clock. The Second type is i80-System interface that
uses address, data, chip select, read/write control and register/status indicating signal. In this type of LCD driver, it
has a frame buffer and has the function of self-refresh, so LCD controller updates one still image by writing only
one time to the LCD.
