ENABLE
DOTCLK
HSYNC
VSYNC
PD17-0
Note 1) In 6-bit interface.mode, one pixel, which consists of R,G, and B, must be transmitted in synchronization
Note 2) VSYNC, HSYNC, EVABLE, DOTCLK, VLD, and PD17-2 should be all transmitted by three clocks.
Note 3) Data to be displayed must be written in the high-speed write mode (HWM =1) in RGB I/F mode.
