15.8. Adjusting CS0 For Special Situations
There are several configuration options in the CS0 module designed to modify the operation of the circuit
and address special situations. In particular, any circuit with more than 500  of series impedance
between the sensor and the device pin may require adjustments for optimal performance. Typical applica-
tions which may require adjustments include the following:


Most systems will require no fine tuning, and the default settings for CS0DT, CS0DR, and CS0IA
should be used.
Touch panel sensors fabricated using a resistive conductor such as indium-tin-oxide (ITO).
Circuits using a high-value series resistor to isolate the sensor element for high ESD protection.
