1. A device comprising:
a detector operable to sense an external device and provide a signal indicating a presence of the external device;
a synchronization controller operable generate data and initialize communication based on the signal; and
a communication device operable to communicate the data,
wherein the data comprises a number of leading synchronization bits, and
the synchronization controller is operable to determine the number based on the signal.
