This register stores the address 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 address of the next uncorrectable error. Storing of the failing address is enabled after reset. When the address width is greater than 32 bits, the most significant bits of the LMB address are read from register address 0x2C4. The register reports the failing word address.

The register is implemented if C_UE_FAILING_REGISTERS is set to 1.
