November 2001 ver 1.2
Font ROM
The HMS81C43xx/GMS87C4060 OSD character size is
fixed as 12dots (Horisontal) * 16dots (Vertical).
1. Each horisontal data (12dots) needs 2byte ROM.
2. One character is constructed with 16 horisontal data to
vertically. As a result, one character needs 32bytes (2 * 16
bytes).
3. HMS81C4332/GMS87C4060 contains 256/512 charac-
ters.
Total Font ROM memory size is calulated as 16,384bytes
( 32bytes / character * 512 character )
4. Font ROM memory is located from 10000
H
~ 13FFF
H
,
this memory can not be accessed by user program.
5. A character’s address and dot position in font ROM is
described in Figure 17-12 .

H
)
Sprite RAM
The HMS81C43xx/GMS87C4060 contains a 32bytes
(12dot * 16dot) sprite RAM.
1. In view point, sprite is similar to character font but it is
not using font ROM.
2. You can selct color by dot unit.
3. Using above 1 and 2, you can make any of patterns what
you want by software. For example, arrow cursor or some-
