s DESCRIPTION
The MB90092 is the display controller for displaying text and graphics on the TV screen.
The MB90092 incorporates display memory (VRAM), a font memory interface, and a video signal generator,
allowing text and graphics to be displayed in conjunction with a small number of external components.
The MB90092 can provide two screens, called the main screen and the sub-screen, either independently or
overlayed one on top of the other.
The main screen consists of 24 characters by 12 lines and allows data to be set for each character. The sub-
screen consists of 32 characters by 12 lines or up to 32 characters by 16 lines. Data can be set either for each
line in the former configuration or collectively for the entire screen in the latter configuration.
For output of video signals, the MB90092 has the composite video signal, Y/C-separated video signal, and RGB
digital output pins. The MB90092 also has video signal input pins, allowing superimpose display over either
composite video signals and Y/C-separated video signals.
