<P>PROBLEM TO BE SOLVED: To provide a debug system for preventing the failure of processing of a user program by a pseudo on-the-fly processing. <P>SOLUTION: The debug system using the pseudo on-the-fly processing is provided with an asynchronous break mask control means for masking an asynchronous break request signal caused by the pseudo on-the-fly processing, according to the priority of user program processing in response to the asynchronous break request signal. Unlike an ordinary break function, the break operation is temporarily held according to the state of the user program. The timing of starting the pseudo on-the-fly processing is made possible to be controlled indirectly from the user program by providing an asynchronous break mask control means. <P>COPYRIGHT: (C)2004,JPO |
