This register stores the ECC of the first occurrence of an access with an uncorrectable error. When the UE_STATUS bit in the ECC Status Register is cleared, this register is re-enabled to store the ECC of the next uncorrectable error. Storing of the failing ECC is enabled after reset.

The register is implemented if C_UE_FAILING_REGISTERS is set to 1.
