11.9 Bus Arbitration Latency
11-62
the delay in asserting the signals.
Another bus arbitration delay occurs when a coprocessor or other device
delays or fails to assert DSACKx or STERM signals to terminate a bus cycle.
The maximum delay in this case is undefined; it depends on the length of
several factors. The MC68030 does not relinquish the physical bus while it
is performing a read-modify-write operation. Since the address translation
search is an extended read-modify-write operation, the no-cache-case latency
is incurred by the longest address translation search required by the system.
In a system that uses the MMU, the bus arbitration latency is affected by
