Impedance is the instantaneous impedance value seen at the input pin of each cap.
sensing pin.
Currently sensed impedance. This impedance reading decreases with the increase of the
capacitance at sensing channel.
When this register reads 0x7F, reference capacitance should be reduced.
When this register reads 0x00, reference capacitance should be increased.
