Title: Method and apparatus for acknowledgement-based handshake mechanism for interactively training links

Abstract: A method and apparatus for advancing initialization messages when initializing an interface is presented. In one embodiment, one of a sequence of training sequence messages are sent in serial mode across the data lanes of a generally-parallel interface between two agents. When one agent correctly receives a fixed number of messages, it may begin sending its messages with an acknowledgement. Thereafter, when that agent correctly receives a fixed number of messages including an acknowledgement, that agent may advance to sending the next training sequence messages in the sequence.
