An apparatus includes a transmitter providing a training pattern on a selected one of n+1 data paths while communicating data on the remaining n of the n+1 data paths. A receiver having adjustment circuitry receives the n+1 data paths and provides n+1 adjusted data paths. The receiver selects a subset of the n+1 adjusted data paths carrying the communicated data while adjusting the selected data path. One method includes sequentially selecting a selected data path from a plurality of data paths coupling a transmitter and a receiver. A training pattern is communicated on the selected data path to the receiver. The selected data path is adjusted in response to the received training pattern.
