5.5 Potentiometer
A single-turn potentiometer is connected as a potential divider to analog input AN000 (Port P40, Pin 56). The
potentiometer can be used to create a voltage between Board_VCC and ground.
Refer to the maker site for specification of the potentiometer (PIHER with part number N6 series).
The potentiometer offers an easy method of supplying a variable analog input to the microcontroller. It does not
necessarily reflect the accuracy of the controller’s ADC. Refer to the RX23T Group Hardware Manual for further details.
