Abstract
A microprocessor capable of functioning in an expanded address mode is disclosed, including: a control unit for determining whether an external instruction is to be used for a normal address mode or to be used for an expanded address mode and for generating control signals; a program counter for generating a first address in response to an output from the control unit during the normal and expanded address modes; an address generator for generating a second address during the expanded address mode, in response to an output from the control unit; an address bus for transferring the first address out of the microprocessor; and a data bus for transferring the second address out of the microprocessor. The microprocessor also includes an address interface circuit for transferring the second address out of the microprocessor through the data bus.
