Abstract
A device contains a first device and a second device. In one embodiment, the first device drives at least three signals, a first reference signal, and a second reference signal. The second device, which is coupled to the first device, receives the at least three signals, the first reference signal, and the second reference signal. The second device identifies values for the at least three signals according to the first reference signal and the second reference signal.
