2.1 BUS SIGNALS
The following signals are used for the MC68306 bus.
2.1.1 Address Bus (A23–A1)
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. During interrupt acknowledge cycles, address lines A1, A2, and A3
provide the level number of the interrupt being acknowledged, and address lines A23–A4
