Note:
The SCAM target may not recognize the Configuration Process Complete function code at the
end of SCAM protocol, and may return to the SCAM Monitor status.
The SCAM target in the ID Unassigned status is the one to which no SCSI ID has been assigned
both explicitly and implicitly. It does not respond to the SCSI selection of the current ID
regardless of the period. The SCAM target can exit from the ID Unassigned status only when it
has detected the start of SCAM protocol, except for the power-on or reset status.
Once the SCAM target has entered the ID Assigned status, it functions as a SCAM tolerant device
with the already assigned ID. That is, it responds to the SCSI selection within the response time of
SCAM tolerant selection but does not respond or recognize the SCAM selection.
The SCAM target can enter the Reset Delay status and allow local initialization by the reset status.
The SCAM target exists this status and enters the SCAM Monitor status within a SCAM reset to
SCAM selection delay.

Level-2 SCAM target
Figure 1.37 shows the operations of level-2 SCAM target. Its status names are explained later.
The RESET condition can terminate all operations in any status, and it forces the SCAM target to
the Reset Delay status.
