Abstract
A microprocessor has a memory part including a memory for storing programs, a central processing unit for carrying out an operation on a data stored in the memory part depending on the programs stored in the memory, a holding part for entering an address region information with a predetermined timing and for holding the address region information, which indicates an allocation of a predetermined address region for the memory, an address generating part for generating an address of a command which is to be executed next, and an access enable part for enabling access to the memory when the address generated by the address generating part is included in the predetermined address region.
