Fast-160 SCSI devices shall not change timing parameters between training or reset events.
Note: (14) See Fig.1-20,21,22,23,24 for measurement points for the timing specifications. (15) SCSI bus
timing values specified by the maximum transfer rate for the given range shall apply even if a
slower transfer rate within the given range is negotiated.
