8.10.4 Memory for OSD
There are 2 types of memory for OSD : OSD ROM (addresses
10000
16
to 11FFF
16
) used to store character dot data and OSD RAM
(addresses 0600
16
to 06B7
16
) used to specify the characters and
colors to be displayed.
Fig. 8.10.11 Character Font Data Storing Address
(1) OSD ROM (addresses 10000
16
to 11FFF
16
)
The dot pattern data for OSD characters is stored in OSD ROM. To
specify the kinds of the character font, it is necessary to write the
character code (Table 8.10.3) into the OSD RAM.
The OSD ROM has a capacity of 8K bytes. Since 32 bytes are re-
quired for 1 character data, the ROM can stores up to 256 kinds of
characters.
The OSD ROM space is broadly divided into 2 areas. The [vertical
16 dots]
[horizontal (left side) 8 dots] data of display characters are
stored in addresses 10000
16
to 107FF
16
and 11000
16
to 117FF
16
;
the [vertical 16 dots]
[horizontal (right side) 4 dots] data of display
characters are stored in addresses 10800
16
to 10FFF
16
and 11800
16
to 11FFF
16
(refer to Figure 8.10.11). Note however that the high-
order 4 bits in the data to be written to addresses 10800
16
to 10FFF
16
and 11800
16
to 11FFF
16
must be set to “1” (by writing data “FX
16
”).
Data of the character font is specified shown in Figure 8.10.11.
