UNCERRSEV[0] - Uncorrectable Error Severity For ESI
Port
This register indicates the severity of the uncorrectable errors for the ESI port. 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 corresponding 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.
