(3) Timeout procedure
If the TARG cannot detect a response (BSY signal) from the INIT when the Selection Timeout
Delay or longer has passed after starting the RESELECTION phase, the timeout procedure shall be
performed though one of the following schemes:
1) The TARG asserts the TRUE signal and generates an RESET condition.
2) The INIT maintains SEL and I/O signals true and stops sending the SCSI ID to the data bus.
Subsequently, the INIT waits for the response from TARG for at least Selection Abort Time +
Deskew Delay × 2. If no response is detected, the INIT releases the SEL and I/O signals
allowing the SCSI bus to go to the BUS FREE phase. If the INIT detects the response from
the TARG during this period, the INIT considers the SELECTION phase to have completed
normally.
The IDD performs process 2) above as RESELECTION phase time-out processing.
