34.4.21 PXP Overlay Color Key High (HW_PXP_OLCOLORKEYHIGH)
This register contains the color key high 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.
