Max Read Request Size (MRRS) — RO. Hardwired to 0.
Enable No Snoop (ENS) — RO. Not supported. The root port will never issue non-snoop requests.
Aux Power PM Enable (APME) — R/W. The OS will set this bit to 1 if the device connected has
detected aux power. It has no effect on the root port otherwise.
Phantom Functions Enable (PFE) — RO. Not supported.
Extended Tag Field Enable (ETFE) — RO. Not supported.
Max Payload Size (MPS) — R/W. The root port only supports 128-B payloads, regardless of the
programming of this field.
Enable Relaxed Ordering (ERO) — RO. Not supported.
Unsupported Request Reporting Enable (URE) — R/W.
0 = The root port will ignore unsupported request errors.
1 = The root port will generate errors when detecting an unsupported request.
Fatal Error Reporting Enable (FEE) — R/W.
0 = The root port will ignore fatal errors.
1 = The root port will generate errors when detecting a fatal error.
Non-Fatal Error Reporting Enable (NFE) — R/W.
0 = The root port will ignore non-fatal errors.
1 = The root port will generate errors when detecting a non-fatal error.
