HD66789
Preliminary
18-bit RGB interface
The 18-bit RGB interface is selected by setting RIM1-0 bits to 00. The display operation is synchronized
with VSYNC, HSYNC, and DOTCLK signals. Display data are transmitted to RAM in synchronization
with the display operation through 18-bit RGB data bus (PD17-0) according to the data valid signal (VLD),
and the data enable signal (ENABLE).
The instructions are set only through a system interface.
