    Abstract: Disclosed herein are system, apparatus, methods and/or combinations and sub-combinations thereof, for using a read data strobe signal received at a host device from a peripheral device to convey variable latency (flow) control or report an error in the data content read from the peripheral device. Reception of the read data strobe signal before a predetermined maximum latency time, provides variable latency control back to the host by indicating when valid data is available for capture. If the read data strobe signal is not received before expiration of a predetermined maximum latency time, the peripheral controller is indicating a read data error back to the host.
