Patent ID: 8423850

Claim:
A system debugging method for a debugger to control a microcomputer having a debugging support circuit for supporting a system debugging, comprising the following steps: when wireless communication is performed between the microcomputer and the debugger in accordance with a pulse transmission technique based on magnetic field coupling by oppositely placing a first coil arrangement included in the microcomputer and a second coil arrangement coupled to the debugger; operating the microcomputer to perform a process of configuring a communication condition of the wireless communication during an initialization operation; operating the microcomputer to await control from the debugger via the debugging support circuit when the microcomputer establishes communication with the debugger; and operating the debugger to await establishment of the communication and to proceed with control of the microcomputer in accordance with the wireless communication, wherein the debugger performs wireless communication with the microcomputer via a magnetic field coupling interface IC having a second transceiver circuit and a second control circuit, the second transceiver circuit being coupled with the second coil arrangement at one side and with the debugger at another side, and the second control circuit is coupled with the debugger and provides the second transceiver circuit with a communication condition based on magnetic field coupling, and wherein the microcomputer performs wireless communication with the debugger through operations of a first transceiver circuit and a first control circuit, the first transceiver circuit being coupled with the first coil arrangement, and the first control circuit providing the first transceiver circuit with a communication condition based on magnetic field coupling.
