    capsensor with analog mux

      hi there.




      I would like to use a circle type electrode as both button type capsensor and other use. 


      so, I tried use a amux to change path to the circle type electrode.




      if amux set 0, the path is ( first setting ) 


      CapSense_CSD -> mux -> the circle type electrode


      if amux set 1, the path is ( second setting )


      another circuit -> mux -> the circle type electrode 




      the problem is.. when i use the first setting the capsensor button shows always ON state. 


      when mux is disabled,  capsensor works fine. so I think activated mux should changes capsensor working condition.




      I have thought that the mux is just switch.... the above condition says another properties of mux must be exist..
