This field selects the pixel format for the 

sprite/Sprite B. Pixel formats with an alpha channel should not use source keying. 

Before entering the blender, each source format is converted to 10 bits per pixel (details 

are described in the intermediate precision for the blender section of the Display 

Functions chapter). 

0000 = YUV 4:2:2 packed (see byte order below).  

0001 = Reserved 

0010 = 8-bpp Indexed. 

0011 = Reserved. 

0100 = Reserved. 

0101 = 16-bit BGRX (5:6:5:0) pixel format (XGA compatible). 

0110 = 32-bit BGRX (8:8:8:8) pixel format. Ignore alpha. 

0111 = 32-bit BGRA (8:8:8:8) pixel format with pre-multiplied alpha channel. 

1000 = 32-bit RGBX (10:10:10:2) pixel format. Ignore alpha. 

1001 = 32-bit RGBA (10:10:10:2) pixel format 

1010 = Reserved. 

1011 = Reserved. 

1100 = Reserved. 

1101 = Reserved. 

1110 = 32-bit RGBX (8:8:8:8) pixel format. Ignore alpha. 

1111 = 32-bit RGBA (8:8:8:8)

When used as a sprite in the 16/32-bpp modes 

without alpha this enables source color keying. Sprite pixel values that match (within 

range) the key will become transparent. Setting this bit is not allowed when the Sprite B 

pixel format includes an alpha channel. 

[DevBW] Erratum: This bit must always be set to 0 when Sprite B pixel format is YUV 

0 = Sprite source key is disabled (default) 

1 = Sprite source key is enabled.

RW

This cause the display plane to duplicate lines and pixels sent to 

the assigned pipe. In the line/pixel doubling mode, the horizontal pixels are doubled and 

lines are sent twice. This is a method of scaling the source image by two (both H and V). 

00 = No line/Pixel duplication 

01 = Line/Pixel Doubling 

10 = Line Doubling only 

11 = Pixel Doubling only

0b

RW

This bit enables or disables the color conversion 

logic. Color conversion is intended to be used with the formats that support YUV formats 

such as the YUV 4:2:2 packed format and x:8:8:8 and 8:8:8:8 formats. Formats such 

as RGB5:5:5 and 5:6:5 do not have YUV versions.  

0 = Pixel data is sent through the conversion logic (only applies to YUV formats) 

1 = Pixel data is not sent through the YUV-)RGB conversion logic.

0b

RW

This bit specifies the source YUV format for the YUV to RGB color 

conversion operation. This field is ignored when source data is RGB. 

0 = ITU-R Recommendation BT.601 

1 = ITU-R Recommendation BT.709

0b

RW

This field is used to select the byte order when using YUV 4:2:2 

data formats. For other formats, this field is ignored.  

00 = YUYV 

01 = UYVY 

10 = YVYU 

11 = VYUY

RW

This mode causes the display plane to be rotated 180 . In 

addition to setting this bit, software must also set the base address to the lower right 

corner of the unrotated image and calculate the x, y offset as relative to the lower right 

corner. 

0 = No rotation 

1 = 180 rotation
