1. A device comprising:
- a data transceiver adapted to be coupled to one or more data lanes of a device-to-device interconnection (DDI);
a negotiation section comprising;
logic to detect 8B/10B code groups on each data lane of the DDI; and
configuration logic to selectively configure the data transceiver to transmit and receive data on the DDI according to a data transmission mode based upon the detected 8B/10B code groups.

Abstract
Disclosed are a system, method and device for negotiating a data transmission mode over an attachment unit interface (DDI). A data transceiver circuit may be coupled to one or more data lanes of the DDI. A negotiation section may receive a link pulse signal on at least one data lane in the DDI during a negotiation period and selectively configure the data transceiver to transmit and receive data on one or more data lanes according to a data transmission mode based upon the received link pulse signal.
