Quantum Instruments DLT 7000 manual Mode Select 6 / 10 Command 15h / 55h, Mode Parameter List

SCSI Commands

MODE SELECT (6) / (10) Command (15h) / (55h) (continued)

Table 5–35 MODE SELECT (6)/(10) Command Descriptor Block - Field Descriptions

Field Name	Description
PF	Page Format. The Page Format bit indicates that the data sent by the host after the
	MODE SELECT header and block descriptors complies with the definition of pages in
	the SCSI-2 specification. The SCSI-1 format will not be implemented so this bit must
	be set to 1. It is an ILLEGAL REQUEST to have page parameters while the PF bit is 0.
SP	Save Parameters. Must be 0. If set, this bit instructs the drive to save all savable pages,
	and this is not supported on the tape drive.
