Abstract: PROBLEM TO BE SOLVED: To provide a data processing system capable of reducing the overhead of programming. SOLUTION: This data processing system has a CPU for performing access through a memory managing interface to various memories including a non- volatile memory. The memory managing interface supports the paging of a module in the non-volatile memory into a paged memory area specified in a memory map. Memory control registers 80-87 for controlling the programming and erasure of the non-volatile memory module are simultaneously mapped onto a memory map in the specified memory register area. In this case, pages 90-97 of the non-volatile memory and memory control registers 80-87 related to them are selected based on a single page selection register and mapped into the specified area inside the memory map.
