DESCRIPTION
MB90092 display controller displaying text graphics screen. MB90092 incorporates display memory (VRAM), font memory interface, video signal generator, allowing text graphics displayed conjunction with small number external components. MB90092 provide screens, called main screen sub-screen, either independently overlayed other. main screen consists characters lines allows data each character. sub-screen consists characters lines characters lines. Data either each line former configuration collectively entire screen latter configuration. characters supported MB90092 normal characters made dots 32-dot graphic characters that displayed eight different colors character units. filled with only graphic characters, main screen (horizontal) (vertical) dots. same case, sub-screen (horizontal) (vertical) dots, (horizontal) (vertical) dots. (The actual display screen depends clock frequency horizontal direction number rasters television system vertical direction.) MB90092 uses font memory, enabling free graphics display. MB90092 16384 types characters including normal graphic characters total. control bits external font memory. output video signals, MB90092 composite video signal, Y/C-separated video signal, digital output pins. MB90092 also video signal input pins, allowing superimpose display over either composite video signals Y/C-separated video signals.

CHARACTER DISPLAY FUNCTIONS
character display functions available normal character display mode MB90092 include: "pattern background display" displaying arbitrarily shaped patterns around character dots, "solid-fill background display" filling entire character cell made dots with background color, "shaded background display" adding shading perimeter solid-fill background, "blink display" blinking. MB90092 also provides "kanji font display" functions framing boldfacing kanji fonts (such kanji font) easier viewing.
GRAPHIC CHARACTER DISPLAY FUNCTIONS
MB90092 display graphic characters well normal characters. Graphic characters consist dots each which displayed color selected from among eight different colors. Color display information included font data. character size same that normal characters. (One graphic characters equivalent three dots normal characters.) Graphic character display following features: configuration Main screen display Display control dots (horizontal vertical)
Normal graphic characters selected each character displayed same time. (Mixed display enabled only extended graphics mode) Display character color colors (for each dot) phases (for each character) gradient colors (color monochrome specified entire screen) Sub-screen display Display control Normal graphic characters selected each line displayed same time. (Mixed display enabled only extended graphics mode) Display character color colors (for each dot) phases (for each line) gradient colors (color monochrome specified entire screen)
Note: specify graphic display those characters kanji font area. Otherwise, they cannot displayed correctly.
