Abstract: Systems and methods for bus clock line handover are disclosed. In one aspect, a clock line in a bus is driven continuously during bus handover without having contentious or contradictory drive signals being provided. After arbitration, an original bus master will drive the clock line to a predetermined value until detecting a state change on a data line. An incoming bus master will begin driving the clock line to the predetermined value and then drive a state change on the data line. This state change is the state change detected by the original bus master that causes the original bus master to stop driving the clock line.
