Patent ID: 7746811

Claim:
An apparatus including a time shared bi-directional serial signaling system, comprising: a differential signal path to convey a serial data signal having a data signal interval including first, second and third subintervals and an embedded clock; host transceiver circuitry coupled to said differential signal path, responsive to reception of a data clock, a plurality of primary forward data and a plurality of secondary forward data by providing primary and secondary forward portions of said serial data signal and said embedded clock as a forward portion of said serial data signal during at least said first and second subintervals, and responsive to reception of a return portion of said serial data signal by retrieving a plurality of return data; and target transceiver circuitry coupled to said differential signal path, responsive to reception of said forward portion of said serial data signal by retrieving said data clock, said plurality of primary forward data and said plurality of secondary forward data, and responsive to reception of a plurality of return data by providing said return portion of said serial data signal during said third subinterval.
