The microcomputer according to the present invention is prepared with differing address space for use during normal operations and during rewrite control, whereby, when modifying a rewrite control program, the production of new user code/data can be avoided for cases in which there are actually no modifications of the user code/data. In other words, the microcomputer switches between user ROM during normal operation and rewrite control ROM during rewrite control, and user code/data and rewrite control program are arranged in differing address space.
