    Abstract: A timing circuit may be enabled when a static signal disables communication through a communications bus, the timing circuit producing a threshold level after being enabled for a predetermined time period, and a switch controlled by the timing circuit is configured to disconnect the static signal when the timing circuit produces the threshold level. A static signal may be used to enable a timing circuit upon the static signal disabling communication through a communications bus, and communication may be allowed through the communication bus by disconnecting the static signal using a switch controlled by the timing circuit, after the timing circuit has been enabled for a predetermined period of time.
