PURPOSE:To surely and effectively confirm that an initialization time unfixing circuit is satisfactorily set by a program by detecting that the data are written into the initialization time unfixing circuit included in a microcomputer pseudo operating circuit based on a program and then displaying the state of the initialization time unfixing circuit. CONSTITUTION:The operation of a program is monitored by a debug circuit 3 to check whether the program stored in an emulation memory 2 has the missetting of the initial value or not. Then a fact that the data are written into an initialization time unfixing circuit included in a microcomputer pseudo operating circuit is detected by a comparator 4 and an unfixed register buffer 5 and then displayed on a monitor 8 of a host machine 7. Thus a circuit that is set by a program and a circuit that is not set yet can be effectively checked in a short time among those initialization unfixing circuits. Then the useless time and cost can be unnecessitated. |
