0 = No limit exists on the amount of data transferred per connection
(default). The drive does not have to disconnect until all requested
data is transferred.
1 to FFFFh = The maximum amount of data that the drive can trans-
fer, in 512-byte increments, before disconnecting, if the initiator
granted the disconnect capability.
Reserved
All reserved bits must be 0.
On read operations, the drive disconnects when the drive buffer is empty, even if the
Allocation Length has not been satisfied. On write operations, the drive disconnects
when the drive buffer is full, even if the Transfer Length has not been exhausted.
Control Mode Page
The Control Mode page specifies whether the drive generates a Check Condition when
any log parameter reaches maximum. (Refer to the Log Select command and the Log
Sense command.) It also specifies whether tagged queueing is used and the behavior of
the drive autoload sequence.
Note:
Autoload Mode persists across power cycles. Its new definition takes effect
at the next cartridge insertion after Mode Select.
