Message In support
Name | Code | Support |
|
|
|
Command Complete | 00h | This message is sent by the drive at the end of the status phase to |
|
| indicate that a command is complete. Once the message is sent, the |
|
| drive releases the bus and goes to Bus Free. |
|
|
|
Disconnect | 04h | This message is sent by the drive to indicate that it is about to |
|
| disconnect from the bus and go to Bus Free. During a Data phase, it is |
|
| always |
|
| Reject message is received in response to this message, then the |
|
| disconnect is prevented. |
|
|
|
Extended Message | 01h | See “Extended Message Support” below. |
|
|
|
Identify | 8Xh | The Identify In message is sent to the initiator during reconnect to |
|
| indicate which Logical Unit is reconnecting. |
|
|
|
Ignore Wide Residue | 23h | This message is sent by the drive to the host to indicate that a byte on |
|
| a wide bus is not valid. |
|
| This is supported whenever a wide transfer is active. It should be sent |
|
| at the end of the data phase. The standard action of the drive is to |
|
| send this message between the data phase and the status phase with |
|
| no disconnect. |
|
|
|
Message Reject | 07h | This message is sent to the initiator when the message received by the |
|
| drive is unsupported or inappropriate. |
|
|
|
Restore Pointers | 03h | This message causes the initiator to reset its data transfer pointers to |
|
| the values they held when the last save data pointers message was |
|
| sent. It will be sent when a parity error is detected on the bus or when |
|
| an Initiator Detected Error message is received in order to retry the |
|
| data phase. |
|
|
|
Save Data Pointers | 02h | This message instructs the initiator to save its current data transfer |
|
| pointers for use with a subsequent Restore pointers message. This |
|
| message will always be sent before a Disconnect message during |
|
| data phases. |
