    PSOC4  touch design issue


      In the touch design, the recommend Cmod is 2.2 nf.  What will happen, if I use 1.1 nf capacitance as the modulation capacitance?

      How to choose a suitable value capacitor?   After all, different product have different Cp.


      I choose 1K resistor between the MCU touch IO and touch sensor.  What is the effect of the size of this resistor?
