Video Color Mask. This mask is a 24-bit RGB value. Zeros in the mask cause the corre-
sponding bits in the graphics or video stream to be forced to match.
For example:
A mask of FFFFFFh causes all 24 bits to be compared (single color match).
A mask of 000000h causes none of the 24 bits to be compared (all colors match).
For more information about the color-key, see VP Memory Offset "028h" on page 477.
The video color mask is used to mask bits of the graphics or video stream being com-
pared to the color-key. It allows a range of values to be used as the color-key.
Description
Reserved (Read Only). Reads back as 0.
Gamma Address. Specifies the address to be used for the next access to the Palette
Data register (VP Memory Offset 040h[23:0]). Each access to the PDR automatically
increments the PAR. If non-sequential access is made to the palette, the PAR must be
loaded between each non-sequential data block.
