(Note 1) Commands without executing disconnect processing: In cases only where commands are issued
without a tag, queuing processing (see Section 1.4) and disconnect processing cannot be
performed in the execution sequence.
(Note 2) Commands with executing disconnect processing: Regardless of command queuing, in a command’s
execution process (after the COMMAND phase is completed, or during or after the completion of data
transfer), disconnect processing is performed. However, in the case of commands with a data state (in
cases where it is hit in the cache, etc.), or with a number of processing modes, other than cases where
the command is in a queue, disconnect processing may not be executed depending on the processing
content specification of the command.
