Abstract
Methods and devices for communicating or interacting by a pen or a stylus with a digitizer are disclosed. An example method describes determining whether the device is to transmit a first information to the digitizer via the electrode or receive a second information from the digitizer via the electrode. An example device for use with the method includes a transmitter circuit, a receiver circuit, and an electrode. The method further includes isolating the electrode from the transmitter circuit in response to determining that the device is to receive the second information from the digitizer via the electrode.
