Notes:
[1] See the SCSI-2 Interface Product Manual (part number 77738479), Section 4.5.
[2] Maximum SCSI asynchronous interface transfer rate is given in Section 5.3.
[3] Synchronous transfer period is determined by negotiations between an initiator and a drive. The
drive is capable of setting periods as given in Section 11.5 in this manual. See Sections 3.1.5.2
and 3.5.3.2 of the SCSI-2 Interface Product Manual for a description of synchronous data
transfer operation.
General timing diagrams for SCSI interface operation are shown in the SCSI-2 Interface Product
Manual, Section 4.5.
