This register stores the decoded address (Bits[55:32]) of the first occurrence of an access with an uncorrectable error. The address format is defined in the Error Address section. In addition, the upper byte of this register stores the ecc_multiple signal. 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.
