PURPOSE:To facilitate the debugging jobs of hardware by carrying out a written test program via a CPU set into a device to be debugged. CONSTITUTION:A control part 13 writes a test program stored in a nonvolatile memory part 14 into a dual port RAM part 15 via a 2nd port 22 based on the input of a key switch 12. Then the test program of the part 15 is read out after receiving an access from a CPU of a device to be debugged via a 1st port 21 connected to a connector 16 for ROM receptacle. That is, the test program is carried out. Thus it, is possible to obtain an inexpensive hardware debugger that can facilitate the debugging jobs. |
