Status

Figure 1.4 shows the type of status that the IDD supports.
The status is one byte of information sent from the TARG to the INIT in the STATUS phase when one
command is completed, and notifies the INIT of the results of the command's execution. The status is
also sent even in cases when the TARG is in a state which it makes it impossible for it to execute the
command when it receives a request for an input/output operation. However, if the command is cleared
by switching to the BUS FREE phase forcibly through an ABORT TASK SET message, an ABORT
TASK message, a CLEAR TASK SET message, a TARGET RESET message, a RESET condition or a
SCSI bus error state, etc., the status for that command is not reported.
After the TARG reports the status in the STATUS phase, it will always send a TASK COMPLETE
message or a LINKED TASK COMPLETE (WITH FLAG) message to notify the INIT of the validity of
the status.
