4.5.13 Color Registers

Theseregisters areusedin8BPP displaymodewithan

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.

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.

• 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.
