s SCREEN CONFIGURATION

The MB90092 provides two screens: the main screen on which data can be set for each character and the sub-

screen 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.

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 × 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 × 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)
