Abstract:
1. A computing device comprising: a sensor controller configured to control operations of a human-touch capacitive sensor module; a near-field communication (NFC) controller configured to control operations of an NFC module; and a plurality of communication lines including a first communication line and a second communication line, each of the first and second communication lines being connected to the sensor controller and the NFC controller such that control signals are transferred between the sensor controller and the NFC controller to synchronize the operations of the human-touch capacitive sensor module and the operations of the NFC module, wherein the sensor controller is configured to assert an active sensor control signal on the first communication line and control the human-touch capacitive sensor module to start a sensor scan to determine whether any touch signals exist within an active area of the human-touch capacitive sensor module when an active NFC control signal is not asserted by the NFC controller on the second communication line, wherein the sensor controller is configured to drive the active sensor control signal until the sensor scan is complete, wherein the NFC controller is configured to assert the active NFC control signal on the second communication line and control the NFC module to start an NFC scan when the active sensor control signal is not asserted by the sensor controller on the first communication line.
