controller sets the AC97_STS bit in the GPE0_STS register (PMBASE +28h). The
AC97_STS bit is shared by AC ’97 and Intel High Definition Audio functions since
they are mutually exclusive.
If software attempts to write a value of 01b or 10b in to this field, the write
operation must complete normally; however, the data is discarded and no state
change occurs.
When in the D3
configuration space is available, but the I/O and memory space are not.
Additionally, interrupts are blocked.
When software changes this value from D3
warm (soft) reset is generated, and software must re-initialize the function.
