摘要

2085891 9120160 PCTABS00009 A controller (12) for use in a local area network includes an arbitration circuit that permits data communication between a processor (10) and a buffer memory (20) associated with the controller (12) to take priority over data communication between controller (12) and buffer memory (20). The arbitration circuit interrupts a controller-initiated read or write cycle upon the receipt of a read or write memory access request from the processor (10).
