The OSD RAM for character is allocated at addresses 0400
character code specification part, color code 1 specification part, and color code 2 specification part
for each block. The number of characters for 1 block (32- or 42-character mode) is selected by bit 1 of
the OSD control register 4. Tables 2.16.3 to 2.16.7 show the address map.
For example, to display 1 character position (the left edge) in block 1, write the character code in
address 0400
OSD RAM is shown in Figure 2.16.25.
Notes 1: Be sure to set a software wait to access to OSD RAM.

Accordingly, maximum 22 characters (32-character mode)/28 characters (42-character
mode) are only displayed in 1 block. Blocks with dot size of 1T
blocks on the layer 1. The RAM data for the 3nth character does not effect the display. Any
character data can be stored here. And also, note the following only in 32-character mode.
As the character is displayed in the 28th’s character area in 42-character mode, set ordi-
narily.
In OSDL mode: all dot size.

The character is not displayed, and only the left 1/3 part of the 22nd character back
ground is displayed in the 22nd’s character area. When not displaying this back-
ground, set transparent for character background color.
Set a blank character or a character of transparent color to the 22nd character.
The character is not displayed, and color palette color specified by bits 3 to 6 of color
code 1 can be output in the 22nd’s character area (left 1/3 part).
