2 : The character code of “0916” is premised on using it as a character
of “transparent space”.
Therefore, set “0016” to the 40-byte addresses corresponding to the
character code “0916.”

(2) OSD RAM
The RAM for OSD is allocated at addresses 080016 to 087F16, and
is divided into a display character code specification part, and a color
code specification part per block. Table 8.10.2 shows the contents of
the OSD RAM.
For example, to display the first character position (the left edge) in
block 1, write the character code in address 080016, and write the
color code at 082016.
The structure of the OSD RAM is shown in Figure 8.10.17.
