BYTE	BIT	VALUE		DESCRIPTION
6	0	0		A value of 0 indicates EDRC Compacted data transfer mode is used.
		1	A value of 1 is used to select EDRC Clear data transfer mode.
				Any other value will default to EDRC Compacted data transfer mode.
7	0-7			Number of milliseconds of delay inserted between each block to be transferred.
8	0-7			The length in KBytes (1 KByte = 1024 bytes) of each block to be transferred.
9-11	0-7			The number of blocks to be transferred. A value of zero is used to transfer from log-
				ical BOT to logical EOT.
12-13	0-7			A 16 bit data pattern to use for the first block written to tape. The same data pattern is
				used throughout the block.
14-15	0-7			A 16 bit value added to each subsequent block after the first block to be used to mod-
				ify each block written. A value of 0 will cause every block to be written with the
				same data pattern. A most significant bit of 1 in this field has the effect of decrement-
				ing each block.
16-19	0-7			Block number. In Space/Locate operations, this is the block number to move to. In
				other operations, the value in this field will have no effect.
20-23	0-7			Number of Filemarks to Space/Locate past. In other operations, the value in this field
				will have no effect.
24-27	0-7			Number of Filemarks to locate to in Space/Locate operations. In other operations,
				the value in this field will have no effect.

A description of each Manufacturing Routine is provided in Chapter 8.

Selection of a Manufacturing Routine is achieved by assigning the routine number, execute count, and any other parameters (in bytes 6-27) associated with tests to be executed in the given Manu- facturing Routine. Values in any field not used by a test in the given Manufacturing Routine are ignored.

Selection of a Manufacturing Routine requires that both the DevOfl and UnitOfl bits must be set to

1.If either of these bits is not set to 1, a CHECK CONDITION is returned with the sense key set to ILLEGAL REQUEST and the ASC set to INVALID FIELD IN PARAMETER LIST.

If any error condition is encountered during the execution of a routine, diagnostic result data is generated at that time nd no further diagnostic execution occurs.
