Abstract
A bus cycle trapping system includes at least one register, a north bridge, a south bridge and a central processing unit (CPU). The register is configured to store at least one trapping parameter. The north bridge traps a bus cycle matching the at least one trapping parameter while issuing an activating signal. The south bridge sends a system management interrupt message according to the activating signal. The CPU enters a system management mode according to the system management interrupt and executes a system management interrupt routine for doing a debugging test of the bus cycle matching the trapping parameter.
