我看手册上说关于显示的的第三中模式是用FIFO模式，我想问下坛子里谁用过那个东西，想请教一下，希望好心人把思路说一下，谢谢。
s5pv210手册里的内容：
1.3.2.1 Interface
The display controller supports three types of interfaces:
• The first type is the conventional RGB interface, which uses RGB data, vertical/ horizontal sync, data valid
signal, and data sync clock.
• The second type is the indirect i80 Interface, which uses address, data, chip select, read/ write control, and
register/ status indicating signal. The LCD driver using i80 Interface contains a frame buffer and can self-
refresh, so the display controller updates one still image by writing only one time to the LCD.
• The third type is FIFO interface with CAMIF2 for writeback.
