Abstract
A digital communication circuit that avoids bit collisions between an external communication device and a controller that communicate to each other through a bi-directional serial communication link is disclosed. The digital communication circuit includes digital circuitry that receives and transmits a digital communication signal. A detection circuit detects when a digital communication signal is being received. And delay circuitry receives the transmitted digital communication signal and responsively produces a delay signal to delay the detection of the received digital communication signal.
