Table 81 Command Error information

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.
