Abstract
A system and method for transmitting client phase information to a host device over a bidirectional data link is described. Embodiments include detecting a phase of a clock signal relative to a data signal transmitted between a host device and a client device over a bidirectional data link. The data link includes one or more data lines each configured to transmit a corresponding bit of the data signal. The phase is encoded as client phase information and transmitted between the host and client device over the one or more data lines. The client phase information is transmitted during an electrical turnaround time period of the bidirectional data link between a read and write operation over the data link.
