• UAI (Unit Attention Inhibit) bit is not used during normal operation when the UAI jumper is removed from the drive. It
may however be changed by the user with no effects. If the UAI jumper is added to the drive, then this bit controls the
generation of unit attention conditions.
• MRG (Merge Glist into Plist) bit is set to 1 for merging the Glist entries into the Plist during FORMAT UNIT command.
• ASDPE (Additional Save Data Pointer Enable) bit is used to control the sending of additional save data pointers mes-
sages. When set it will cause a save data pointers message to be sent on every disconnection. This bit is only used by
the Target after the Default Mode parameter values are overridden with the Saved values that are read from the
Reserved Area of the media as a part of the motor startup sequence. Before the Saved values are read from the
Reserved Area of the media, the Save Data Pointer message is always sent to the Initiator prior to disconnection.
When not set, a save data pointers message is sent only if the current connection contained a data phase and a further
data phase will be required to complete the command.
• VGMDE (Veggie Mode) bit indicates the drive, during it's idle state, will execute random seeks at a predefined rate and
range of cylinders using a predefined head.
• CMDAC (Command Active) bit in conjunction with LED Mode bits determines if an LED on the drive is activated
while commands are active. If CMDAC bit is one and LED Mode bits are zero, an LED driver is active when a com-
mand is queued or executed.
