System and method for supporting split transactions on a bus. The method may comprise processing a periodic frame list of external bus data frame by frame, and traversing each frame node by node. When a save place node is encountered in a first frame, the traversing jumps to a destination node pointed to by the save place node in a second frame, and continues the traversing there. When a restore place node is encountered when traversing the nodes in the second frame, the traversing returns to the node after the save place node in the first frame and continues the processing in the first frame. The method may be implemented on a system that comprises a processor, a memory, an internal bus, and an external bus controller. The external bus controller and the external bus data may support one or more versions of the Universal Serial Bus standard.
