Notes.
[1] See the Timing examples section of the SCSI Interface Product Manual.
[2] Maximum SCSI asynchronous interface transfer rate is given in Section 4.2.3 of this manual.
[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 the Synchronous data transfer section and the
Extended messages section of the SCSI Command Reference Manual for a description of synchronous
data transfer operation.
