Description
Reserved (Read Only). Reads back as 0.
Palette Data. Contains the read or write data for a Gamma Correction RAM (palette).
Provides the video palette data. The data can be read or written to the Gamma Correc-
tion RAM (palette) via this register. Prior to accessing this register, an appropriate
address should be loaded to the PAR (VP Memory Offset 038h[7:0]). Subsequent
accesses to the PDR cause the internal address counter to be incremented for the next
cycle.
Note:
Description
Reserved (Read Only). Reads back as 0.
Enable. Enable Saturation Scaling. If this bit is cleared, saturation conversion does not
occur. If it is set, saturation conversion and scaling occurs prior to YUV conversion of the
graphics.
SPARE. Bit is R/W but has no function.
Saturation Scale. Saturation scale value set by software to scale the saturation value
derived by the RGB to HSV conversion of the graphics. After scaling the S value, the
result is then converted to YUV format prior to blending with the video. This 8-bit value
represents 256 equal steps between 0 and 1.
RSVD
When a read or write to the Gamma Correction RAM occurs, the previous output
value is held for one additional DOTCLK period. This effect should go unnoticed
during normal operation.
