The bus monitor ensures that each bus cycle is terminated within a reasonable period of time. The USIU
provides a bus monitor option to monitor internal to external bus accesses on the external bus. The monitor
counts from transfer start to transfer acknowledge and from transfer acknowledge to transfer acknowledge
within bursts. If the monitor times out, transfer error acknowledge (TEA) is asserted internally by the
