can be removed if required to isolate or change the User Switch from the default MCU pin.

15.4 ADC Rotary Potentiometers

The EVB incorporates a couple of ADC Rotary Potentiometer [which routes a voltage between 0v to VD_HV_A] directly connected to
ADC Precise Input Chanel of the S32K3XX Microcontroller.
