Abstract

PURPOSE: To provide a means to optionally rewrite or read externally specified contents of input/output circuit or accumulator and the like by externally giving read/write instruction signal for specified address and data, external access demand signal.
CONSTITUTION: When an external specification address 18, external data 19, read/write instruction signal are given to an address pointer 22, data resister 23, read/write control circuit 21, and external access demand signal 16 is input to an external access demand control circuit 20 during the execution of a control cycle, the input/output of an accumulator 7, input/output circuits 8, 9 are changed over to the address pointer 22, data resister 23by an address change over circuit 24, data change over circuit 25 after the present cycle in execution is completed to read or rewrite the contents of the accumulator 7 or input/output circuits 8, 9.
