(1) COMMAND COMPLETE (X©00π) : MESSAGE IN phase (target Æ initiator)
This message indicates that a command has been terminated and a valid status has
been reported to the initiator.
The target always reports the COMMAND COMPLETE message after the
STATUS phase at the completion of the input/output operation. (This requirement
also applies if the COMMAND phase is not executed because of a command cannot
be received.)
Uopn receiving the COMMAND COMPLETE message, the initiator knows that a
command has terminated.
After sending the COMMAND COMPLETE message, the target switches into the
BUS FREE phase.
If the COMMAND COMPLETE message is rejected with the MESSAGE REJECT
message, this scanner switches into the BUS FREE phase.

(initiator Æ target)
This message indicates that the initiator detected a retriable error and intends to
request the target for retry. The value of the current pointer is not guaranteed.
The initiator does not intend to issue another message by activating ATN before it
deactivaes the ACK of the INITIATOR DETECTED ERROR message.
