1. There are zero-ohm resistors on the direct connections between each USER_SWx and the MCU pins. These can be removed
if required to isolate or change the User Switch from the default MCU pin.
11.3 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 S32K312 Microcontroller.
