Abstract
A suspended or stuck condition of a serial bus controller is released by applying an artificial clock signal to the stuck bus controller in place of the normally applied clock signal. The artificial clock signal causes the stuck controller to advance in a communication transaction which was in progress when the stuck condition occurred, until a data signal is supplied at a logical level which permits the initiation of another transaction in accordance with the serial communication protocol of the bus. The ability to release the stuck condition avoids losing important data and other information that would be lost if the stuck condition was released by performing a reset of the stuck controller or the component to which it is connected.
