Display Controller Register Descriptions
6.6.7
The Pallette Access registers are used for accessing the internal palette RAM and extensions. In addition to the standard
256 entries for color translation, the palette has extensions for cursor colors and overscan (border) color.
The diagnotics registers enable testability of the display FIFO and compression FIFO.

PAL Address. This 9-bit field specifies the address to be used for the next access to the
DC_PAL_DATA register (DC Memory Offset 074h). Each access to the data register auto-
matically increments the palette address register. If non-sequential access is made to the
palette, the address register must be loaded between each non-sequential data block. The
address ranges are as follows:
Address
Note that in general, 24-bit values are loaded for all color extensions. However, if a 16-bpp
mode is active, only the appropriate most significant bits are used (5:5:5 or 5:6:5).
