Abstract:
1. A method of redefining a first logic threshold and a second logic threshold for a hibernation state of a digital data interface communication system, the method comprising the steps of: sending a link shut down packet from a host to a client wherein a first logic level and a second logic level determine the first logic threshold of at least one data receiver; disabling at least one data driver and placing its output into a high impedance state by the host wherein a third logic level and a fourth logic level determine the second threshold of at least one hibernation receiver and wherein the fourth logic level is produced by the disabled at least one data driver in the high impedance state; sending a wake up pulse to the at least one hibernation receiver, wherein the wake up pulse comprises outputting the third Logic level; and detecting the wake up pulse by the: at least one hibernation receiver.
