ABSTRACT:
In the microcomputer, the debug target circuit and the debugging circuit with an interface module to the in-circuit emulator are independently supplied with drive powers. Drive power is supplied to the debug target circuit and the debugging circuit, and various debug information is set by the in-circuit emulator. Thereafter, only supply of drive power to the debug target circuit is stopped. While the various debug information is held at the debugging circuit, supply of drive power to the debug target circuit is restarted. The debugging just after power throw-in is performed based on the debug information held in the debugging circuit.
