5.1 ADDRESS BUS (A31–A0)
These three-state bidirectional signals provide the address of the first item of a bus
transfer (except for acknowledge transfers) when the M68040 is the bus master. When an
alternate bus master is controlling the bus, the processor examines (snoops) these signals
to determine whether the processor should intervene in the access to maintain cache
coherency.
The level on CDIS can select a multiplexed bus mode during processor reset, which
allows the address bus and data bus to be physically tied together for multiplexed bus
