4.5.13 Color Registers
The Color Registers group consists of two 32-bit registers
located at GX_BASE+8360h-8368h. These registers are
described below and Table 4-34 gives their bit formats.
These registers are used in 8 BPP display mode with an
external RAMDAC for passing cursor and border color
indices to the palette in the RAMDAC. For the flat panel
color translation, the cursor and border color data is
loaded into palette extensions as described in the Palette
Access Registers section.
•
Display Controller Cursor Color
(DC_CURSOR_COLOR)
-
Contains the 8-bit indices for the cursor colors.
•
Display Controller Border Color
(DC_BORDER_COLOR)
Contains the 8-bit index for the border or overscan color.
