2.16.7 Character Color
As shown in Figure 2.16.26, there are 16 built-in color codes. Color palette 0 is fixed at transparent, and
color palette 8 is fixed at black. The remaining 14 colors can be set to any of the 512 colors available. The
setting procedure for character colors is as follows:
• CC mode ........................................ 8 kinds
Color palette selection range (color palettes 0 to 7 or 8 to 15) can be selected by bit 0 of the OSD control
register 3 (address 020716). Color palettes are set by bits RC11 to RC13 of the OSD RAM from among
the selection range.
• OSDS/L/P mode ........................... 16 kinds
Color palettes are set by bits RC11 to RC14 of the OSD RAM.
• CDOSD mode ............................... 16 kinds
Color palettes are set in dot units according to CD font data.
Only in CDOSD mode, a dot which selects color palette 0 or 8 is colored to the color palette set by RC13
to RC16 of OSD RAM in character units (refer to Figure 2.16.28).
• SPRITE display ............................ 16 kinds
Color palettes are set in dot units according to the CD font data.
Notes 1: Color palette 8 is always selected for bordering and solid space output (OUT 1 output) regardless
of the set value in the register.
2: Color palette 0 (transparent) and the transparent setting of other color palettes will differ. When
there are multiple layers overlapping (on top of each other, piled up), and the priority layer is color
palette 0 (transparent), the bottom layer is displayed, but if the priority layer is the transparent
setting of any other color palette, the background is displayed without displaying the bottom layer
(refer to Figure 2.16.28).
2.16.8 Character Background Color
The display area around the characters can be colored in with a character background color. Character
background colors are set in character units.
• CC mode ........................................ 4 kinds
Color palette selection range (color codes 0 to 3, 4 to 7, 8 to 11, or 12 to 15) can be selected by bits 1 and
2 of the OSD control register 3 (address 020716). Color palettes are set by bits RC20 and RC21 of the
OSD RAM from among the selection range.
• OSDS/L/P mode ........................... 16 kinds
Color palettes are set by bits RC15, RC16, RC20, and RC21 of the OSD RAM.
Note: The character background is displayed in the following part:
(character display area) – (character font) – (border).
Accordingly, the character background color and the color signal for these two sections cannot be
mixed.
