External Display Interface
The following interfaces are available as the external display interface (RGB interface). The interface is
selected by setting RIM1-0 bits. RAM is accessible through the RGB interface.

RGB interface
Through the RGB-I/F, the display operation is performed in synchronization with VSYNC, HSYNC, and
DOTCLK. The RGB interface enables data transmission with low power consumption by overwriting the
area that needs update in high-speed write mode in combination with the window address function. The
front and back porches must be set before and after the display period.
VSYNC: Frame synchronization signal
HSYNC: Raster-row synchronization signal
DOTCLK: Dot clock
Back porch period (BPP):14H>=BP3-0>=2H
Front porch period (FPP):14H>=FP3-0>=2H
Display operation period: NL4-0 =< 240H
The number of raster-rows of 1 frame: FPP + DP + BPP
FPP + BPP =< 16H
ENABLE: Data enable signal
VLD: Data valid signal
PD17-0: Display data for RGB (6:6:6)

Note 1) The front porch period continues until the next input
of VSYNC signal.
Note 3)In RGB interface mode, VSYNC, HSYNC, and DOTCLK more than to achieve the LCD resolution must be supplied.
Note 2) The DOTCLK signal must be supplied consecutively.
