With only 2 processors, it shouldn't really matter that much, but it's still a choice you need to make. Then tie that line high or low on both processors. For CPA, do you want each processor to be able to interrupt DMA's in progress? If not, don't connect CPA to anything. Connect BR1->BR1 and BR2->BR2 on both processors. Make sure one processor is ID1 and the other is ID2. Tie BR3 thru BR6 high on both processors. Sounds like a fun project! Patience, persistence, truth, Dr. mike |
