ABSTRACT:
A single-chip microcomputer is disclosed, which comprises a central processing unit including a programmable counter for storing address data for accessing a first memory and performing operations and control, a register for setting address data of a second memory and a coincidence circuit. When the contents of the register and programmable counter coincide, the coincidence circuit provides an instruction to the central processing unit. Thus, the central processing unit accesses an address of the second memory in lieu of an address of the first memory, in which an undesired instruction in stored, according to data in the first memory. Subsequently, the second memory address is accessed in lieu of the first memory address with the undesired instruction therein.
