The multi-master bus system (,) comprises further an arbiter (,) for performing bus arbitration, arbiter (,) having logic for conditionally subsequently granting the bus (,) to a master of an initiating transaction for a closing transaction depending on the transaction type value of the slave of the initiating transaction.
