<strong>RA8806</strong><br />
Two Layers Character/Graphic LCD Controller<br />
6-2 Driver Interface<br />
The main function of Driver Interface is to generate Frame (Pin “FR”), Latch Pulse (Pin “LP”), “YD” and<br />
Data Bus (LD[7:0]) for external LCD driver IC. <strong>RA8806</strong> could both support 4-bits and 8-bits LCD driver<br />
interface. Pin “DW” is for LCD driver data bus selection. If “DW” pulls high then 8-bits LCD driver is used.<br />
If pull low then 4-bits LCD driver is used. Figure 6-8 is the LCD interface of <strong>RA8806</strong>.<br />
