SPRITE_A_ENABLE:
This bit will enable or disable the Sprite A. When this bit is set,
the plane will generate pixels for display to be combined by the blender for the target
pipe. 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. This bit only has an effect when the plane
is not trusted. When the plane is marked trusted, this bit will be overridden and the
display disabled when the registers are unlocked.
1 = Enable
0 = Disable

SPRITE_A_GAMMA_ENABLE:
There are two gamma adjustments possible in the
Sprite A data path. This bit controls the gamma correction in the display pipe not the
gamma control in this plane. It affects only the pixel data from this display plane. For
pixel format of 8-bit indexed, this bit should be set to a one. Gamma correction logic
that is contained in the Sprite A logic is disabled by loading the default values into those
registers.
When this plane is marked as trusted, this bit should always be set to zero to force the
pipe gamma to be always be bypassed.
0 = Sprite A pixel data bypasses the display pipe gamma correction logic (default).
1 = Sprite A pixel data is gamma corrected in the pipe gamma correction logic

SPRITE_A_SOURCE_PIXEL_FORMAT:
This field selects the pixel format for the
sprite/Sprite A. 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.
