If any of the disconnected state commands are received by the FSC
when it is not in the disconnected state, the command is ignored, the

Table 5.3
This command causes the FSC target to arbitrate for the bus and then
enter the Reselection phase when it wins arbitration. The Identify
message, required by SCSI protocol, must either be placed in the FIFO
by the microprocessor before issuing the command; or must be
transferred by DMA, which involves setting the transfer count to one and
setting up the external DMA controller. In either case, the

The sequence terminates early if a Reselect time-out occurs. If it
terminates normally, a Function Complete interrupt occurs.
