RAM ACCESS via RGB INTERFACE & SYSTEM INTERFACE
All the data for display is written to the internal RAM in the S6D0114 when RGB interface is in use. In this method,
data, including that in both the motion picture area and the screen update frame, can only be transferred via RGB
interface. In addition to using the high-speed write mode (HWM = 1) and the window address function, the power
consumption can be reduced and high-speed access can be achieved while motion pictures are being displayed.
Data for display that is not in the motion picture area or the screen update frame can be written via the 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.
