を特徴とするマイクロプログラム制御装置。 In a microprogram control device, which is a method of controlling electronic equipment, there is a decoder that outputs a flag when the executed microinstruction is not a jump instruction, or if it is a jump instruction but does not jump because the condition is not met, and a decoder that outputs a flag when the executed microinstruction is a jump instruction. and a decoder that outputs the flag when the condition is met and the jump occurs, a rewritable memory that writes the above two flags to the same address as the microinstruction, and a means for reading the contents of the rewritable memory from the outside. A microprogram control device comprising:
