S6D0114 132-RGB X 176-DOT 1-CHIP DRIVER IC FOR 262,144-COLOR TFT-LCD DISPLAY

INTERFACE SPECIFICATION
The S6D0114 incorporates a system interface, which is used to set instructions, and an external display interface,
which is used to display motion pictures. Selecting these interfaces to match the screen data (motion picture or still
picture) enables efficient transfer of data for display.
The external display interface includes RGB interface and VSYNC interface. This allows flicker-free screen update.
When RGB interface is selected, the synchronization signals (VSYNC, HSYNC, and DOTCLK) are available for use
in operating the display. The data for display (PD17-0) is written according to the values of the data enable signal
(ENABLE) and data valid signal (VLD), in synchronization with the VSYNC, HSYNC, and DOTCLK signals. In
addition, using the window address function enables rewriting only to the internal RAM area to display motion
pictures. Using this function also enables simultaneously display of the motion picture area and the RAM data that
was written.
While displaying motion pictures, the data for display should be written in high-speed write mode, which achieves
both low power consumption and high-speed access via RGB interface or VSYNC interface.
The internal display operation is synchronized with the frame synchronization signal (VSYNC) in VSYNC interface
mode. When writing to the internal RAM is done within the required time after the falling edge of VSYNC, motion
pictures can be displayed via the conventional interface. There are some limitations on the timing and methods of
writing to RAM. See the section on the external display interface.
The S6D0114 has four operation modes for each display state. These settings are specified by control instructions
for external display interface. Transitions between modes should follow the transition flow.

NOTES:
1) Instruction registers can only be set via system interface.
2) RGB interface and VSYNC interface cannot be used at the same time.
3) RGB interface mode cannot be set during operations.
4) For mode transitions, see the section on the external display interface.
5) RGB interface VSYNC interface modes should be used in high-speed write mode (HWM = 1).
