Abstract
A processor performs data transactions. For a first data transfer between the processor and a first external device which uses non-multiplexed data transactions, a first address is placed on an (external) address bus and first data is transferred on an (external) address/data bus. A second data transaction is performed between the processor and a second external device which uses multiplexed data transactions. In an address phase of the second data transaction, a second address is placed on the address/data bus. In a data phase of the second transaction, second data is transferred on the address/data bus.
