<p><P>PROBLEM TO BE SOLVED: To provide a debug device capable of switching the control of a normal program and a debug program without using any interrupting signal. <P>SOLUTION: When a chip select signal 105 is outputted from an address comparison circuit 101 for detecting that a program execution address is matched with a preliminarily set address, a debug program stored in a system memory 104 is switched from a normal program stored in a user memory 103 which is being executed by an MCU 102 so as to be executed, and the normal program stored in the user memory 103 is switched from the debug program stored in the system memory 104 so as to be executed according to the chip select signal 105. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
