Unsupported Request Error Status Severity | Intel 41210 specification

Register Description

12.2.54Offset 10Ch: ERRUNC_SEV—PCI Express* Uncorrectable Error Severity

This register controls whether an individual uncorrectable error is reported as a fatal error. An uncorrectable error is reported as fatal when the corresponding error bit in this register is set. When the bit is cleared, the corresponding error is considered non-fatal.
