Abstract:
A signal generating circuit of a peripheral device for sending a frame information structure (FIS) to a host via a serial transmission channel to change a busy bit representing the state of the peripheral device. The signal generating circuit includes a trigger generator and a signal generator. The trigger generator generates a trigger signal by monitoring a control signal of the signal generating circuit. The signal generator, coupled to the trigger generator, generates the indication according to the trigger signal.
