Max Read Request Size — RO. Hardwired to 0 enabling 128B maximum read request size.
No Snoop Enable (NSNPEN) — R/W.
0 = The Intel High Definition Audio controller will not set the No Snoop bit. In this case, isochronous
1 = The Intel High Definition Audio controller is permitted to set the No Snoop bit in the Requester
Note: This bit is not reset on D3
Auxiliary Power Enable — RO. Hardwired to 0, indicating that Intel High Definition Audio device
does not draw AUX power
Phantom Function Enable — RO. Hardwired to 0 disabling phantom functions.
Extended Tag Field Enable — RO. Hardwired to 0 enabling 5-bit tag.
Max Payload Size — RO. Hardwired to 0 indicating 128B.
Enable Relaxed Ordering — RO. Hardwired to 0 disabling relaxed ordering.
Unsupported Request Reporting Enable — RO. Not implemented. Hardwired to 0.
Fatal Error Reporting Enable — RO. Not implemented. Hardwired to 0.
Non-Fatal Error Reporting Enable — RO. Not implemented. Hardwired to 0.
Correctable Error Reporting Enable — RO. Not implemented. Hardwired to 0.
