摘要：PURPOSE: A program counter controlled processor is provided to detect and eliminate noise generated during an execution of a program so that it can be stably operated, namely prevent a wrong operation caused by a noise. CONSTITUTION: The processor comprises a voltage level detector(10), a control program counter(20), a program counter(30), and an internal address bus(40). The voltage level detector(10) detects a voltage generated by a noise. The control program counter(20) generates a preset address for coping with a wrong operation caused by the noise. The program counter(30) receives the address signal, and outputs an address signal, to be increased one by one, to the internal address bus(40). A switch, SW, switches the address, generated by the control program counter(20), to the program counter(30) by the signal output from the voltage level detector(10).
