ON-Screen Display Controller (OSDC-360)
MB90092
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 24 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. The characters supported by the MB90092 are the normal characters made up of 24 by 32 dots and the 8 x 32-dot graphic characters that can be displayed in any of eight different colors in character units. If filled with only graphic characters, the main screen is 192 (horizontal) x 384 (vertical) dots. In the same case, the sub-screen is 192 (horizontal) x 384 (vertical) dots, or 256 (horizontal) x 512 (vertical) dots. (The actual display screen depends on the dot clock frequency in the horizontal direction and on the number of rasters of the television system in the vertical direction.) The MB90092 uses RAM as font memory, enabling free graphics display. The MB90092 can use up to 16384 types of characters including normal and graphic characters in total. It can control up to 16M bits of external font memory. 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.

s SCREEN CONFIGURATION
The MB90092 provides two screens: the main screen on which data can be set for each character and the subscreen on which data can be set for each line (or for the entire screen). The overall background can be represented using the screen background color. Figure 4 shows an example of main screen and sub-screen merged.

Screen background color display
Figure 4 Example of Main Screen and Sub-Screen Merged
1. Main screen configuration
The main screen displays up to 24 characters by 12 lines. It offers a choice of two display modes: the normal mode for displaying only normal characters and the extended graphics mode in which both normal and graphic characters can be displayed, selectable character by character. Main Screen Features * * * * * * * Normal mode and extended graphics mode Screen configuration: 24 characters x 12 lines (data settable for each character) Character sizes: Five different types (selectable for each line) Line spacing: 0 to 15 rasters Display position control (Vertical: In raster units, Horizontal: In 1/3-character units) Setting display priority over the sub-screen (for each line) Output control (for each line)
2. Sub-screen configuration
The sub-screen offers a choice of two screen modes: the normal screen mode on which data can be set for each line and the full-screen moe A or B for full-screen display. In the normal screen mode, the sub-screen displays up to 32 characters by 12 lines. The number of horizontal characters can range from 1 to 32 (1, 2, 4, 8, 16, 24, or 32 characters) depends on the SG2-SG0 setting of command 11 (sub-screen control). Setting the code for the character to be displayed at the left end of each line allows a string of continuous characters of the same character code (address) to be displayed as many as the specified number of horizontal characters. The full-screen mode enables display using the entire screen (screen display area: 32 characters x 16 lines). Setting the code for the character to be displayed at the upper left corner of the screen allows a string of continuous characters of the same character code to be displayed on the entire screen. Full-screen mode A or B is selected depending on the display area setting. Sub-screen Features * * * * Normal screen mode/full-screen mode A/full-screen mode B Display position control (Vertical: In raster units, Horizontal: In 2-dot units) Setting display priority over the main screen (for each line on the main screen) Output control (for each line) 43

s CHARACTER CONFIGURATION
1. Normal and Graphic Characters
The MB90092 can display two types of characters: normal characters and graphic characters. Normal characters each consist of 24 horizontal dots x 32 vertical dots. Graphic characters each consists of 8 horizontal dots x 32 vertical dots. The normal and graphic characters are the same in size (3 horizontal dots for normal characters equal to one horizontal dot for graphic characters). The display color can be set for each dot of only graphic characters. Figure 5 shows character configuration examples. (1) Normal character configuration example: 24 dots
32 dots

2. Character Sizes
Five different character sizes are available: standard, double width, double height, double width x double height, and double height x quadruple width. The character size can be specified for only the main screen. The sub-screen can display only the standard size of characters. Figure 6 shows character configuration examples of each character size. (1) Standard character size 24 dots (2) Double width character size 48 dots
32 dots

(3) Double height character size 24 dots
64 dots

(5) Double height x quadruple width character size 96 dots
64 dots
Note: The number of horizontal dots is based on the normal character dot as a unit dot. One dot for graphic characters is equivalent to three horizontal dots for normal characters. Figure 6 Zoom-in display function
2. Zoom-in display function
The zoom-in display function displays each character on the main screen using 48 vertical dots by vertically doubling only the upper 24 dots of font data which is 32 dots in height. Characters enlarged by the zoom-in function can be further enlarged by separately specifying the desired character size.

s CHARACTER DISPLAY FUNCTIONS
The character display functions available in the normal character display mode of the MB90092 include: "pattern background display" for displaying arbitrarily shaped patterns around character dots, "solid-fill background display" for filling the entire character cell made up of 24 x 32 dots with a background color, "shaded background display" for adding 3D shading to the perimeter of the solid-fill background, and "blink display" for blinking. The MB90092 also provides "kanji font display" functions for framing and boldfacing of kanji fonts (such as the kanji ROM font) for easier viewing.
s GRAPHIC CHARACTER DISPLAY FUNCTIONS
The MB90092 can display graphic characters as well as normal characters. Graphic characters consist of 8 x 32 dots each of which can be displayed in the color selected from among eight different colors. Color display information is included in font data. The character size is the same as that of normal characters. (One dot for graphic characters is equivalent to three dots for normal characters.) Graphic character display has the following features: * Dot configuration * Main screen display * Display control * * * * : 8 x 32 dots (horizontal x vertical)
: Normal and graphic characters selected for each character can be displayed at the same time. (Mixed display enabled only in extended graphics mode) Display character color : 8 colors (for each dot) x 4 phases (for each character) or 8 gradient colors (color or monochrome specified for the entire screen) Sub-screen display Display control : Normal and graphic characters selected for each line can be displayed at the same time. (Mixed display enabled only in extended graphics mode) Display character color : 8 colors (for each dot) x 4 phases (for each line) or 8 gradient colors (color or monochrome specified for the entire screen)
Note: Do not specify graphic display for those characters in the kanji font area. Otherwise, they cannot be displayed correctly.
