Table 13. Contents of OSD RAM
RAM for OSD (addresses 0800
16
to 0FF7
16
)
The RAM for OSD is allocated at addresses 0800
16
to 0FF7
16
, and
is divided into a display character code specification part, color code
1 specification part, and color code 2 specification part for each block.
Table 13 shows the contents of the RAM for OSD.
For example, to display 1 character position (the left edge) in block
1, write the character code in address 0800
16
, write color code 1 at
0840
16
, and write color code 2 at 0828
16
.
The structure of the RAM for OSD is shown in Figure 82.
Note:
For the OSD mode block with dot size of 1.5T
C
1/2H and
1.5T
C
1H, the 3nth (n = 1 to 13) character is skipped as
compared with ordinary block
8
. Accordingly, maximum 27 char-
acters (the right 1/3 part of the 27th's character area is not
displayed) are only displayed in 1 block. The RAM data for the
3nth character does not effect the display. Any character data
can be stored here (refer to Figure 81).
Mask version has maximum 24 characters in 1 block when
programming.
