Note: The 120-byte addresses corresponding to the character code “07F16,”
“08016” and “17F16” in OSD ROM are the test data storing area. Set
“FF16” to the area. (We stores the test data to this area and the different
data from “FF16” is stored for the actual products.)

OSD RAM (addresses 080016 to 087716)
The OSD RAM for character is allocated at addresses 080016 to
084716, 085016 to 085716, 086016 to 086716, 087016 to 087716, and
is divided into a display character code specification part 087016 to
087716, and color/attribute specification part for each block. Tables
8.10.3 shows the contents of the OSD RAM.
For example, to display 1 character position (the left edge) in block 1,
write the character code in address 080016, write color/attribute code
at 081016.
The structure of the OSD RAM is shown in Figure 8.10.18.
