.. note::
#) Bit 7 is the most significant bit;
#) The value of a = alpha bits is undefined when reading from the driver,
ignored when writing to the driver, except when alpha blending has
been negotiated for a :ref:`Video Overlay <overlay>` or
:ref:`Video Output Overlay <osd>` for the formats Y444, YUV555 and
YUV4. However, for formats AYUV32 and VUYA32, the alpha component is
expected to contain a meaningful value that can be used by drivers
and applications. And, the formats XYUV32 and VUYX32 contain undefined
alpha values that must be ignored by all applications and drivers.
