1. A method comprising:
negotiating a communication capability between a stylus and a digitizer system of a touch-enabled device, wherein negotiating the communication capability comprises at least one of:
receiving an instruction from the digitizer system at the stylus that instructs the stylus to configure a transmission protocol thereof based on a capability of the touch-enabled device, or
transmitting an instruction from the stylus to the digitizer system that instructs the digitizer system to configure a transmission protocol thereof to accommodate input from the stylus;
receiving a synchronization signal at the stylus, the synchronization signal defined based on at least one of a capability of the stylus or the capability of the touch-enabled device; and
communicating with the digitizer system using the synchronization signal with the stylus.
