Patent abstract
A method for determining direction of signal transmission in a bi-directional signal line, including sampling data signals at two terminals, A and B, enabling data flow from A to B when data flow from B to A is not enabled, and a logical 0 bit is sampled at A, enabling data flow from B to A when data flow from A to B is not enabled, and a logical 0 bit is sampled at B, disabling data flow from A to B when data flow from A to B is enabled and two successive logical 1 bits are sampled at A, and disabling data flow from B to A when data flow from B to A is enabled and two successive logical 1 bits are sampled at B. An electrical circuit is also described and claimed.
