MOVING PICTURE DISPLAY
The S6D0114 incorporates RGB interface to display motion pictures and RAM to store data for display.
For displaying motion pictures, the S6D0114 has the following features.
- Motion picture area can only be transferred by the window address function.
- The high-speed write mode achieves both low power consumption and high-speed access.
- Motion picture area to be rewritten can only be transferred.
- Reducing the amount of data transferred enables reduce the power consumption to the whole system.
- Still picture area, such as an icon, can be updated while displaying motion pictures combining with the system
interface.
RAM ACCESS VIA RGB INTERFACE AND SYSTEM INTERFACE
RAM can be accessed via the system interface when RGB interface is in use. When data is written to RAM during
RGB interface mode, the ENABLE bit should be low to stop data writing via RGB interface, because RAM writing is
always performed in synchronization with the DOTCLK input when ENABLE is high. After this RAM access via the
system interface, a waiting time is needed for a write/read bus cycle before the next RAM access starts via RGB
interface. When a RAM write conflict occurs, data writing is not guaranteed.
Example of display motion picture via RGB-I/F and updating still picture via the system interface are shown below.
