Advance Information
Datasheet
The processor can stall (BSTALL asserted) even with an empty bus queue (BREQ deasserted).
Depending on the instruction stream and memory wait states, the two signals can be separated by
several CLKIN cycles.
Bus arbitration logic that logically “ANDs” BSTALL and BREQ will not correctly grant the bus to
the processor in all stall cases, potentially degrading processor performance.
Do not logically “AND” BSTALL and BREQ together in arbitration logic. Instead, the simplest
bus arbitration should logically “OR” BSTALL and BREQ to determine the processor’s bus
ownership requirements.
More sophisticated arbitration should recognize the priority nature of these two signals. Using a
traffic light analogy, BREQ is a “yellow light” warning of a possible processor stall and BSTALL
is a “red light” indicating a stall in progress.
