(2) OSD RAM
The RAM for OSD is allocated at addresses 080016 to 087F16, 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 8.11.3 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 the color code 1
at 082016.
The structure of the OSD RAM is shown in Figure 8.11.16.
