3.1
This 23-bit, unidirectional, three-state bus is capable of addressing 16 Mbytes of data.
This bus provides the address for bus operation during all cycles except interrupt
acknowledge cycles and breakpoint cycles. During interrupt acknowledge cycles, address
lines A1, A2, and A3 provide the level number of the interrupt being acknowledged, and
address lines A23–A4 are driven to logic high.
