Uncorrectable Error Severity Register
The uncorrectable error severity register controls the reporting of individual errors as ERR_FATAL or
ERR_NONFATAL. When a bit is set, the corresponding error condition is identified as fatal. When a bit is
cleared, the corresponding error condition is identified as nonfatal. See Table 5−4 for a complete description
of the register contents.
