13.1.27 DSTS—Device Status Register (PCI Express*—D28:F0/F1/
F2/F3/F4/F5/F6/F7)
Address Offset: 4Ah–4Bh Attribute: R/WC, RO
Default Value: 0010h Size: 16 bits
1 Non-Fatal Error Reporting Enable (NFE) — R/W.
0 = The root port will ignore non-fatal errors.
1 = Enables signaling of ERR_NONFATAL to the Root Control register due to internally detected
errors or error messages received across the link. Other bits also control the full scope of
related error reporting.
0 Correctable Error Reporting Enable (CEE) — R/W.
0 = The root port will ignore correctable errors.
1 = Enables signaling of ERR_CORR to the Root Control register due to internally detected errors or
error messages received across the link. Other bits also control the full scope of related error
reporting.
Bit Description
Bit Description
15:6 Reserved
5 Transactions Pending (TDP) — RO. This bit has no meaning for the root port since only one
transaction may be pending to Intel® Xeon® Processor D-1500 Product Family , so a read of this bit
cannot occur until it has already returned to 0.
4 AUX Power Detected (APD) — RO. The root port contains AUX power for wakeup.
3 Unsupported Request Detected (URD) — R/WC. Indicates an unsupported request was detected.
2 Fatal Error Detected (FED) — R/WC. Indicates a fatal error was detected.
0 = Fatal has not occurred.
1 = A fatal error occurred from a data link protocol error, link training error, buffer overflow, or
malformed TLP.
1 Non-Fatal Error Detected (NFED) — R/WC. Indicates a non-fatal error was detected.
0 = Non-fatal has not occurred.
1 = A non-fatal error occurred from a poisoned TLP, unexpected completions, unsupported requests,
completer abort, or completer timeout.
0 Correctable Error Detected (CED) — R/WC. Indicates a correctable error was detected.
0 = Correctable has not occurred.
1 = The port received an internal correctable error from receiver errors / framing errors, TLP CRC
error, DLLP CRC error, replay num rollover, replay timeout.
