Control Data

The control data specifies the display position, size, and color of a character pattern. It is stored at

×××FH

in the CROM area. One control data item consists of 16 bits. The highest bit is always 0. Fig. 20-9 shows

the configuration of the control data.

Control Data Configuration

The control data is provided between two character pattern data items. It has nothing to do with the

character pattern data items at addresses before and after the control code. Any control data can be specified

using data in VRAM.

(1) Horizontal size data (b14 and b13 of control data)

The horizontal size data determines the horizontal size of each image of a character. Each character has

four image sizes (up to three sizes per row). Table 20-7 lists details of the horizontal size data.
