Abstract

A communication system including a physical layer circuit, a timer circuit, and a turnaround controller. The physical layer circuit provides an early turnaround indication upon detection of a turnaround command and before completion of the turnaround command. The timer circuit is programmed with a timeout value indicative of a maximum time of a turnaround procedure initiated by the turnaround command. The turnaround controller starts the timer circuit in response to the early turnaround indication. A transmit controller may begin retrieving information to transmit from a memory in response to the early turnaround indication, and may begin transmitting the retrieved information if the turnaround procedure completes before timeout of the timer circuit. The retrieved information may be configuration information for a sensor. The turnaround controller provides an error indication if the timer circuit times out indicating a turnaround error. The error indication enables remedial action to be taken.
