Abstract
A method and method of mastering a serial bus. A serial bus is monitored in order to detect a quiescent period on the bus. Responsive to a detection of a quiescent period, bus signals to a first master device of the serial bus are interrupted, isolating the first bus master from the rest of the bus. Once the first bus master is isolated, a second bus master may operate on the bus, free from potential deleterious interference from the first bus master. When the second bus master is finished operating, it may cause the re-coupling of the bus, restoring the capability of the first bus master to operate.
