This register stores the ECC bits 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 table describes the register bit usage when DQ_WIDTH = 72.

Table 1. Uncorrectable Error First Failing ECC Register for 72-Bit External Memory Width
Bits	Name	Core Access	Reset Value	Description
7:0	UE_FFE	R	0	ECC (Bits[7:0]) of the first occurrence of an uncorrectable error.

The table describes the register bit usage when DQ_WIDTH = 144.

Table 2. Uncorrectable Error First Failing ECC Register for 144-Bit External Memory Width
Bits	Name	Core Access	Reset Value	Description
15:0	UE_FFE	R	0	ECC (Bits[15:0]) of the first occurrence of an uncorrectable error.
