Integrated circuit including clock controlled debugging circuit and system-on-chip including the same

Abstract

An integrated circuit includes a processor core, a clock control circuit and a debugging circuit. The processor core processes target software. The clock control circuit determines whether an electrical connection exists between the processor core and an external debugger and generates a determination result. The clock control circuit generates an output clock signal based on the determination result. The external debugger performs a debugging operation for the target software. The output clock signal is selectively activated based on the determination result and an input clock signal. The debugging circuit provides information with respect to the debugging operation for the target software to the external debugger based on the output clock signal.
