Abstract
A debugging circuit comprises a debugging interface, a switch unit coupled to the debugging interface, a controller coupled to the switch unit, a platform controller hub (PCH), and a central processing unit (CPU). The PCH and the CPU are coupled to the switch unit. The debugging interface is coupled between the switch unit and a debugging device. The switch unit receives a control signal from the controller, and selectively outputs a first data signal from the PCH or a second data signal from the CPU to the debugging device through the debugging interface according to the control signal.
