Abstract
A debug system includes a chip to be tested and a debug controller. The chip to be tested includes a circuit to be tested, a debug access circuit and a debug protection circuit. When a protection function is not enabled, the debug protection circuit enables a communication between the debug access circuit and the chip to be tested, the debug controller accesses the data of the chip to be tested via the debug access circuit for debugging the circuit to be tested. When the protection function is enabled, the debug protection circuit blocks the communication between the debug access circuit and the chip to be tested, the debug controller transmits a message to the debug protection circuit via the debug access circuit, and the debug protection circuit determines whether to disable the protection function according to the message.
