34.4.18 PXP S0 Color Key Low (HW_PXP_S0COLORKEYLOW)
This register contains the color key low 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

A pointer to a data structure containing register values to be used when processing the next frame.
The pointer must be 32-bit aligned and should reside in on-chip or off-chip memory.
Reserved, always set to zero.
Indicates that the next frame functionality has been enabled. This bit reflects the status of the hardware
semaphore indicating that a reload operation is pending at the end of the current frame.
Reserved, always set to zero.
Low range of RGB color key applied to S0 buffer. To disable S0 colorkeying, set the low colorkey to 0xFFFFFF
and the high colorkey to 0x000000.
