Notes.
[1] See SCSI-2 Interface Manual P/N 77738479 (called Volume 2), Section 4.5
[2] Maximum SCSI asynchronous interface transfer rate is given in Section 4.2.3.
[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 9.5. See also Sections 3.1.5.2 and 3.5.3.2 of the SCSI-2
Interface Product Manual (P/N 77738479) for a description of synchronous data transfer operation.
General timing diagrams for SCSI interface operation are shown in the SCSI-2 Interface Product Manual
P/N 77738479, Section 4.5. The specific timing values that apply to this drive are listed in Table 12.
