6-bit data transmission synchronization
16-bit RGB interface
The 16-bit RGB interface is selected by setting RIM1-0 bits to 01. The display operation is synchronized
with VSYNC, HSYNC, and DOTCLK signals. Display data are transmitted to RAM in synchronization
with the display operation through 16-bit RGB data bus (PD17-13, 11-1) according to the data valid signal
(VLD), and the data enable signal (ENABLE).
The instructions are set only through a system interface.
