12.11.7 Character Color
As shown in Figure 2.11.24, there are 16 built-in color pallets. Color
pallet 0 is fixed at transparent, and color pallet 8 is fixed at black.
The remaining 14 colors can be set to any of the 64 colors available.
The setting procedure for character colors is as follows:
• CC mode ................................. 8 kinds
• OSD mode .............................. 15 kinds
• CDOSD mode ......................... 8 kinds
• SPRITE display ....................... 8 kinds
Notes 1: Color pallet 8 is always selected for bordering and solid space output
Rev. 1.0
Color pallet selection range (color pallets 0 to 7 or 8 to 15) can be
selected by bit 0 of the OSD control register 3 (address 0219
Color pallets are set by bits RC11 to RC13 of the OSD RAM from
among the selection range.
Color pallets are set by bits RC11 to RC14 of the OSD RAM.
Color pallet selection range (color pallets 0 to 7 or 8 to 15) can be
selected by bit 3 of the OSD control register 3 (address 0219
Color pallets are set in dot units according to the CD font data (the
OSD RAM<color dot font> contents)from among the selection
range.
Only in CDOSD mode, a dot which selects color pallet 0 or 8 is
colored to the color pallet set by RC13 to RC16 of OSD RAM in
character units.
Color pallet selection range (color pallets 0 to 7 or 8 to 15) can be
selected by bit 4 of the OSD control register 3 (address 0219
Color pallets are set in dot units according to the CD font data (the
OSD RAM<color dot font> contents) from among the selection
range.
2: Color pallet 0 (transparent) and the transparent setting of other color
(OUT 1 output) regardless of the set value in the register.
pallets will differ. When there are multiple layers overlapping (on top
of each other, piled up), and the priority layer is color pallet 0 (trans-
parent), the bottom layer is displayed, but if the priority layer is the
transparent setting of any other color pallet, the background is dis-
played without displaying the bottom layer (refer to Figure 12.11.26).

12.11.8 Character Background Color
The display area around the characters can be colored in with a char-
acter background color. Character background colors are set in
character units.
• CC mode ................................. 4 kinds
• OSD mode .............................. 15 kinds
Note : The character background is displayed in the following part:
Color pallet selection range (color pallets 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 0219
and RC21 of the OSD RAM from among the selection range.
Color pallets are set by bits RC15, RC16, RC20, and RC21 of the
OSD RAM.

Accordingly, the character background color and the color signal for
these two sections cannot be mixed.
