路のマイクロプログラム制御装置。 A microprogram control device for an integrated circuit includes a microprogram memory that can be written to externally at any time, a converter for its address, a selector for switching input data during writing, a register for storing the address, and a microprogram memory that can be written to from the outside at any time. An integrated circuit microprogram control device comprising a comparator that compares whether the address is among those that have been changed, and a sensor that switches the microprogram output based on the result.
