Abstract
An external area judging unit judges according to an address signal of a CPU whether the access to an external memory or the access to a peripheral unit is desired. In cases where the access to the external memory (or the peripheral unit) is desired, a bus selection signal indicating the external memory (or the peripheral unit) is sent to a bus control unit, and a plurality of bus control signals received in the bus control unit from the CPU are sent to the external memory (or the peripheral unit) as a plurality of external bus signals based on a bus timing for the external memory (or the peripheral unit) to make the CPU gain access to the external memory (or the peripheral unit).
