PROBLEM TO BE SOLVED: To remove restrictions by the mount size by exchanging data needed for debugging between a host system and a target system. SOLUTION: To exchange debugging process data between the host system 1 and target system 2, the host system 1 is equipped with a general communication interface 11 and the target system 2 is equipped with one communication interface 21 selected out of prescribed communication interfaces. Here, the communication interface 21 on the side of the target system 2 is provided with specifications of unique allocation of a port address and functions of respective bit lines of the port. Then the general communication interface 11 of the host system 1 and the communication interface 21 of the target system 2 have necessary signal lines connected through a communication cable line 3 in advance. |
