Notes.
[1] See the SCSI Interface Product Manual, part number 77738479, 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
Interface Product Manual, part number 77738479, for a description of synchronous data transfer opera-
tion.
