A system includes a first device and a second device coupled to a link including two or more data paths and a first portion and a second portion. The first device is to transmit a number of bits corresponding to a message before training the link on the first portion of the link, where the number of bits is equal to a number of the two or more data paths, and where each data path transmits one bit of the number of bits. The second device is to receive the message before training the link. The second device is to perform a decode operation on the number of bits received to determine the corresponding message and transmit a second message or data on the second portion of the link in response to performing the decode operation on the number of bits.
