IO3Severity:Training Error Severity
This field should not be used for setting Training error severity due to a
recent PCI Express Base Specification, Revision 1.0a Errata Dec 2003 to
remove training error. Hardware behavior is undefined.
UNCERRSEV[7:2] - Uncorrectable Error Severity
This register indicates the severity of the uncorrectable errors. An error is reported as
fatal when the corresponding error bit in the severity register is set. If the bit is
cleared, the corresponding error is considered non-fatal. If an error is recorded in the
UNCERRSTS register, the appropriate bit of UNCERRSEV determines if the error gets
reflected as a device fatal or nonfatal error in the PEX_FAT_FERR, PEX_NF_COR_FERR,
PEX_FAT_NERR, PEX_NF_COR_NERR registers.
