Table 165 Queued Error Log data structure definition

The TAG field (Byte 0 Bits 4-0) contains the tag number corresponding to a queued command if the NQ bit is
cleared.
The NQ field (Byte 0 Bit 7) indicates whether the error condition was a result of a non-queued or not. If it is cleared
the error information corresponds to a queued command specified by the tag number indicated in the TAG field.
The bytes 1 to 13 correspond to the contents of Shadow Register Block when the error was reported.
The Data Structure Checksum (Byte 511) contains the 2's complement of the sum of the first 511 bytes in the data
structure. The sum of all 512 bytes of the data structure will be zero when the checksum is correct.
