Uncorrectable Error Mask Register Description (continued) BIT FIELD NAME ACCESS DESCRIPTION 3:0 RSVD R Reserved. Returns 0h when read. 5.5 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.
