ABSTRACT:
Access to a bus is granted to one of a number of requesting communication circuits that each submitted a bus control request during a request period of an arbitration period in response to grant information which can be stored in a primary and a backup priority table. If a requesting communication circuit has an identity and priority that match the identity and priority of a communication circuit stored in a row of the primary or backup priority table that corresponds with the arbitration period, and the identities stored in the tables match only one requesting communication circuit, access to the bus is granted to the requesting communication circuit.
