8.11.6 Memory for OSD
There are 2 types of memory for OSD : OSD ROM (addresses
1080016 to 157FF16 and 1800016 to 1ACFF16) used to specify char-
acter dot data and OSD RAM (addresses 070016 to 07A716 and
080016 to 0FDF16) used to specify the kinds of display characters,
display colors, and SPRITE display. The following describes each
type of memory.
Fig. 8.11.20 Character Font Data Storing Address
(1) OSD ROM (addresses 1080016 to 157FF16, 1800016 to
1ACFF16)
The dot pattern data for OSD characters is stored in the charac-
ter font area in the OSD ROM and the CD font data for OSD
characters is stored in the color dot font area in the OSD ROM.
To specify the kinds of the character font and the CD font, it is
necessary to write the character code into the OSD RAM.
The modes are selected by bit 3 of the OSD control register 3 for
each screen.
The character font data storing address is shown in Figure 8.11.20.
The CD font data storing address is shown in Figure 8.11.21.
The 510 kinds of character font and 62 kinds of CD font can be
stored.

Line number = “0216” to “1516”
Character code = “0016” to “1FF16” (“0FF16” and “10016” can not be used. Write “FF16” to corresponding addresses.)
