Abstract
An asynchronous interface enables the transfer of information between a set of devices operating in a loop and having a wide range of operating speeds. Each device can enter a Controller active state in which it sources command frames to control the loop operation. Each device can also enter a Talker active state in which it sources Data frames on a Listener active state in which it received Data frames. The transfer of frames is coordinated by a set of handshakes which enable the frames to be transferred in an asynchronous manner.
