Programmable Registers
34.4.9 PXP Source 0 (video) Buffer Parameters (HW_PXP_S0PARAM)
This register contains buffer information for the S0 input RGB/YUV buffer.
The S0 Parameter register contains the size of the S0 input buffer (WIDTH, HEIGHT) as
well as provides an offset for the display of this buffer within the output frame buffer
(XBASE,YBASE). All four values are in terms of NxN pixel blocks. In 16 pixel block size
mode, only the low 7 bits of each field can be used and the most significant bit must be set
to 0.
EXAMPLE
HW_PXP_S0PARAM_WR(0x0101281E); // S0 buffer will appear at offset (8,8) in the output buffer.

34.4.10 Source 0 Background Color (HW_PXP_S0BACKGROUND)
S0 Background Pixel Color. This register provides a pixel value used when processing
blocks outside of the region specified by the S0SIZE register. This value can effectively be
used to set the color of the letterboxing region around a video image.
This register contains a pixel value to be used for any S0 blocks that fall outside the S0
extents. This is effectively a background or letterbox color.

This field indicates the horizontal offset location (in NxN block) of the S0 buffer within the output frame buffer.
This field indicates the vertical offset location (in NxN block) of the S0 buffer within the output frame buffer.
Indicates number of horizontal NxN blocks in the image (non-rotated).
Indicates the number of vertical NxN blocks in the image (non-rotated).
