(6) MESSAGE PARITY ERROR (X©09π) : MESSAGE OUT phase (initiator Æ target)
This message indicates that the initiator detected a parity error in the message
received. The target resends only that message.
The initiator does not intend to issue another message by activating ATN before it
deactivates the ACK of the MESSAGE PARITY ERROR message.
Upon receiving the MESSAGE PARITY ERROR message, this scanner takes
action as shown in the following table.
Phase when ATN is detected
MESSAGE IN
Other
*1 This scanner retries three times with the message in the MESSAGE IN phase.
If the third retry fails, this scanner immediately moves to the BUS FREE
phase.
(7) BUS DEVICE RESET (X©0Cπ) : MESSAGE OUT phase (initiator Æ target)
This message addresses any initiators that are operating, or waiting for operation,
on the target. The message initializes those initiators by resetting their input/
output operations.
The BUS DEVICE RESET message is transferred in the asynchronous mode.
This scanner generates the UNIT ATTENTION condition to all initiators.
After being initialized, the initiators move to the BUS FREE phase.
The initiators do not intend to issue another message by activating ATN before
they deactivate the ACK of the BUS DEVICE RESET message.
(8) IDENTIFY (X©80π to X©FFπ) : MESSAGE OUT phase (initiator Æ target)
This message specifies either a logical unit under control of the target, or a process
incorporated in the target (maintenance, self>diagnostic, etc.).
