Programmable Registers
34.4.19 PXP S0 Color Key High (HW_PXP_S0COLORKEYHIGH)
This register contains the color key high value for the S0 buffer.
When processing an image, the if the PXP finds a pixel in the background image with a
color that falls in the range from the S0COLORKEYLOW to S0COLORKEYHIGH range,
it will substitute the color found in the matching overlay. If no overlay is present or if the
overlay also matches its colorkey range, the s0background color is used.
EXAMPLE
HW_PXP_S0COLORKEYLOW_WR (0x008000); // medium green and
HW_PXP_S0COLORKEYHIGH_WR(0x00FF00); // light green

34.4.20 PXP Overlay Color Key Low (HW_PXP_OLCOLORKEYLOW)
This register contains the color key low value for the OL buffer.
When processing an image, the if the PXP finds a pixel in the current overlay image with
a color that falls in the range from the OLCOLORKEYLOW to OLCOLORKEYHIGH
range, it will use the S0 pixel value for that location. If no S0 image is present or if the S0
image also matches its colorkey range, the s0background color is used. Colorkey operations
are higher priority than alpha or ROP operations.
