PURPOSE: A method for a memory addressing and a page mapping of a micro controller is provided to solve a problem generated by a difference of a page for reading data from a page for writing data when an internal memory area of a micro controller is extended to a plurality of pages, to execute addressing of the micro controller internal memory area effectively, and to execute a program easily without a calculation error. CONSTITUTION: A page control signal creation unit(200) creates a register control signal(RegAcc) and a page control signal(PgMode). The register control signal(RegAcc) is enabled when a page including a specific area is accessed. The page control signal(PgMode) is enabled when a predetermined area of a page is accessed and updated. A page selection unit(300) is connected to a bus which reads or writes extended pages. When the register control signal(RegAcc) is enabled, the page selection unit(300) selects only a page including the specific area. When the page control signal(PgMode) is enabled, a multiplexer(400) uses an address of a read page as an address of a page to be written.
