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
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 preceded by a Save Data Pointers
message. If a Message Reject message is
received in response to this message, then
the disconnect is prevented.

is not valid. This will be supported
whenever a wide transfer is active.
