Register Descriptions
3.8.46 EXP_DEVSTS – PCI Express Device Status (D2:F0)
Address Offset: 6E – 6Fh
Access: RO, R/WC
Size: 16 Bits
Default: 0000h
This register provides information about PCI Express device-specific parameters.
1 0b
R/W
Non-Fatal Error Reporting Enable. This bit controls the reporting of nonfatal
errors. Note that the reporting of nonfatal errors is internal to the root. No external
ERR_NONFATAL message is generated. PCICMD[SERRE] when set can also
enable reporting of both internal and external errors to be reported.
0 = Disable nonfatal error reporting
1 = Enable nonfatal error reporting
0 0b
R/W
Correctable Error Reporting Enable. This bit controls the reporting of
correctable errors. Note that the reporting of correctable errors is internal to the
root. No external ERR_CORR message is generated.
0 = Disable correctable error reporting
1 = Enable correctable error reporting

been detected. This bit is set upon Unsupported Request detection regardless of
whether or not error reporting is enabled in the Device Control register. Software
clears this bit by writing a ‘1’ to the bit location.
0 = No Unsupported Request detected
1 = Unsupported Request detected
2 0b
R/WC
Fatal Error Detected. Indicates that a fatal error has been detected. This bit is
set upon fatal error detection regardless of whether or not error reporting is
