Abstract

An integrated circuit includes a monitoring-target circuit portion 1200 and a debugging circuit portion 1100 . The debugging circuit portion 1100 acquires a signal on a signal line of the monitoring-target circuit portion 1200 and transmits the acquired signal to an external device 2000 by radio. The debugging circuit portion 1100 includes a setting unit 1120 and a radio transmitter 1140 . In order to monitor the monitoring-target circuit portion 1200 , the setting unit 1120 sets an isolation unit 1300 so as to make electrical connection between the debugging circuit portion 1100 and the monitoring-target circuit portion 1200 . In addition, the setting unit 1120 sets a selector 1130 to select a signal line 1131 specified as a monitoring target. The radio transmitter 1140 acquires a signal on the signal line selected by the selector 1130 and transmits the acquired signal to the external device 2000 by radio.
