ABSTRACT:
In a one-chip microcomputer, a programmable logic array is interposed between an input/output port and a central processing unit and processes the signals input to the input/output port in accordance with a given program such that the interrupt operation in the microcomputer is controlled by the output of the programmable logic array in response to the signals input to the input/output port. A part of the input/output port may be used as the interrupt terminals, and additionally the control of outer circuits outside of the microcomputer is carried out, independently of the program of the microcomputer, by the output of the programmable logic array in response to the signals input to the input/output port.
