Fair, Priority
Receive
Hold the request if the acceleration of arbitration packet transmitted with
enable is 8 bits (ACK).
Except for 8 bits, the requests are ignored.
Ignore the request when the acceleration of arbitration is disabled.
Grant
Arbitration Won.
Idle, Status
Excluding when the bus reset is generated, Hold the requests.
