5.5 Potentiometer
A single-turn potentiometer is connected as a potential divider to analog input AN115, pin C12. The
potentiometer can be used to create a voltage between VCC18_ADC1 and GROUND.
Refer to the maker site for specification of the potentiometer (PIHER with part number N6L50T7S-103R).
The potentiometer offers an easy method of supplying a variable analog input to the microprocessor. It does not
necessarily reflect the accuracy of the controller’s ADC. Refer to the RZ/T2M Group User’s Manual: Hardware for further
details.
