Abstract
A method and apparatus for a control bus for connection of electronic devices. An embodiment of a method includes coupling a transmitting device to a receiving device, including connecting a control bus between the transmitting device and the receiving device, with the control bus being a bi-directional, single-line bus. The method further includes obtaining control of the control bus for either the transmitting device or the receiving device, with the device obtaining control becoming an initiator and the other device becoming a follower. One or more control signals are converted to one or more data packets, with each of the one or more control signals representing one of multiple different types of control signals. The generated data packets are transmitted from the initiator to the follower via the control bus.
