PURPOSE: To provide an inexpensive program debugging device in which memory data is easy to understand, and a program need not be stopped during the display of the memory data, and the display of the memory data of plural machine built-in type microcomputers is facilitated. CONSTITUTION: The microcomputer 10 is provided with a CPU 13, a ROM 14 in which an application program and a debugging program to be executed by this CPU 13 are stored, a communication interface 12, and a RAM 15. The CPU 13 executes the application program in response to a debugging command through the communication interface 12 from an external device 11, and executes debugging, and informs the external device 11 of this result, and also, rewrites the constant of the RAM 15 by the command of the external device 11. The external device 11 receives the memory data of the RAM 15 through the communication interface 12, and displays this memory data after converting it by the use of a conversion table. |
