Abstract:
A capacitance sensing circuit receives an application of a power supply. The capacitance sensing circuit controls a switch circuit to connect the power supply to a processing device responsive to the application of the power supply. The capacitance sensing circuit receives, via a control interface and from the processing device, control information to configure the capacitance sensing circuit. The capacitance sensing circuit disconnects the power supply from the processing device subsequent to receiving the control information.
