DISPLAY_B_SPRITE_PRIMARY_B_ENABLE:
This bit will enable or disable the
display B/sprite. When this bit is set, the plane will generate pixels for display. When set
to zero, memory fetches cease and display is blanked (from this plane) at the next
VBLANK event from the pipe that this plane is assigned. At least one of the display pipes
must be enabled to enable this plane. There is an override for the enable of this plane in
the Pipe Configuration register.
1 = Enable
0 = Disable

0b
RW
DISPLAY_B_SPRITE_GAMMA_ENABLE:
This bit should only be changed after the
plane has been disabled. It controls the bypassing of the display pipe gamma unit for
this display plane pixel data only. For 8-bit indexed display data, this bit should be set to
a one.
0 = Display B pixel data bypasses the pipe gamma correction logic (default).
1 = Display B pixel data is gamma corrected in the pipe gamma correction logic

DISPLAY_B_SOURCE_PIXEL_FORMAT:
This field selects the pixel format for the
sprite/display B. Pixel formats with an alpha channel (8:8:8:8) 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).
000x = 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 color format)
1000 = 32-bit RGBX (10:10:10:2) pixel format. Ignore alpha.
1001 = 32-bit RGBA (10:10:10:2) pixel format. (with pre-multiplied alpha color format)
1010 = 32-bit BGRX (10:10:10:2) pixel format Ignore alpha
1011 = 32-bit BGRA (10:10:10:2) pixel format (with pre-multiplied alpha color format)
1100 = 64-bit RGBX (16:16:16:16) 16 bit floating point pixel format. Ignore alpha.
1101 = 64-bit RGBA (16:16:16:16) 16-bit floating point pixel format (with pre-
multiplied color format)
1110 = 32-bit RGBX (8:8:8:8) pixel format. Ignore alpha.
1111 = 32-bit RGBA (8:8:8:8) pixel format (with pre-multiplied color format)
