Field Name Bits Type Reset Value Description
UNCORR_ECC_LOG_
DAT_71_64
7:0 ro 0x0 bits [71:64] of the data that caused the captured

the first ECC error if multiple errors occurred
since UNCORR_ECC_LOG_VALID was cleared)
5-bits of ECC are calculated over 8-bits of data.
Bits[68:64] carries these 5-bits. Bits[71:69] are
always 0.
