Status/

Command

Complete

Controls whether the CTS drops

the BSY line quickly (about

5 µsec after the Command

Complete message) or whether

the CTS waits longer to drop the

BSY line to accommodate

drivers that require the BSY line

to be enabled for a longer period

of time.

NORMAL – The CTS manually

reconnects, sends status, and

sends the Command Complete

message to the initiator. The

transaction time before the CTS

drops the BSY line is about

600 µsec.

FAST – The CTS sends status

and the Command Complete

message to the initiator using an

integrated SCSI chip command.

This reduces the time required

for the CTS to drop the BSY line

to about 5 µsec.

EEPROM Options for Selecting Density

This section provides detailed information about two of the MODE

SELECT/MODE SENSE options described in Table A-4. These

options control tape format and data compression.

The True Areal Density Selection option enables you to choose

how the Density Code and the Data Compression Page in the

MODE SELECT command are used to specify the tape format and

data compression.

The Legal Non-LBOT Density option enables you to choose how

the Density Code in the MODE SELECT command functions

when you issue the command and the tape is not positioned at

LBOT.

These EEPROM options are implemented independently. That is, the

setting of one of these EEPROM options does not depend on the

setting of the other.
