Power State (PS) — R/W. This field is used both to determine the current power state
of the Intel High Definition Audio controller and to set a new power state.
00 = D0 state
11 = D3
Others = reserved
NOTES:

Next Capability (Next) — RO. Hardwired to 70h. Points to the PCI Express* capability
structure.
Cap ID (CAP) — RO. Hardwired to 05h. Indicates that this pointer is a MSI capability
Reserved
64b Address Capability (64ADD) — RO. Hardwired to 1. Indicates the ability to generate
a 64-bit message address
Multiple Message Enable (MME) — RO. Normally this is a R/W register. However, since
only 1 message is supported, these bits are hardwired to 000 = 1 message.
Multiple Message Capable (MMC) — RO. Hardwired to 0 indicating request for 1
message.
MSI Enable (ME) — R/W.
0 = MSI may not be generated
1 = MSI will be generated instead of an INTx signal.

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.
