APPARATUS, SYSTEM AND METHOD FOR COMMUNICATION OF TOUCH SENSOR INFORMATION

摘要

Techniques and mechanisms to communicate touch sensor information via physical layer (PHY) circuitry that provides a high speed, low voltage interface. In an embodiment, a source device and a sink device each include a respective differential PHY (D-PHY) and respective protocol logic to support a touch serial interface protocol. Analog circuitry of the sink device receives an output from a touch sensor array, and the respective D-PHYs exchange touch sensor data based on such output. The source device processes digital data based on the exchanged touch sensor data. In another embodiment, any generation of a software interrupt message or a firmware interrupt message in response to identification of an occurrence of a gesture event based on the output is performed after the touch sensor data is received by the sink device.
