A system for phase tracking and equalization across a byte group for asymmetric control of high-speed bidirectional signaling includes a slave device and a master device that is coupled to the slave device via a plurality of bidirectional data paths. The master device may adaptively modify transmit characteristics based upon data eye information sent via one or more unidirectional data paths by the slave device. The data eye information may correspond to an edge position of data signal transitions received by the slave device on each data path of the plurality of bidirectional data paths. In addition, the master device may modify data path equalization coefficients within the master device for a grouping of the bidirectional data paths such as a byte group, for example, dependent upon the data eye information.
