ABSTRACT:
Initialization of a bidirectional, self-timed parallel interface with capacitive coupling is provided. The self-timed interface includes master and slave nodes connected by a parallel bus comprising multiple AC differential wire pairs. The initialization includes automatically testing at least one wire pair of the multiple AC differential wire pairs for conductivity failure, wherein the testing is responsive to a link reset signal of a first frequency. The automatically testing includes employing a link test signal of a second frequency to test the at least one wire pair of the multiple AC differential wire pairs. The second frequency is a lower frequency than a third, operational signal frequency of the self-timed parallel interface, and the first frequency and the second frequency comprise different frequencies. An initialization testing and handshake approach between the master node and slave node is also provided.
