Additionally a pushbutton is provided with the Rotary Encoder. For details please refer to Rotary Encoder
with Pushbutton.
4.2.6 Analog Input - Potentiometer
A potentiometer (POT1) is provided to generate an analog voltage, which can provided to the
microcontroller’s analog input pins.
By turning the potentiometer POT1, a voltage derived from the MCU output signal APO (P0_1)
can be adjusted. The APO signal can be controlled by the Low Power Sampler (LPS) macro. If
the LPS macro is not used, APO has to be set to high manually (use P0_1 as general purpose
digital output).

Please use the following jumper configuration to connect the potentiometers to the
microcontroller:

4.2.7 Rotary Encoder with Pushbutton Switch
An incremental Rotary Encoder (ENC1) is provided on the starter kit. The outputs ENC1_a and
ENC1_b of the Rotary Encoder can be connected to the microcontroller internal encoder timer via
jumpers. In addition the Rotary Encoder (ENC1) incorporates a pushbutton switch ENC1_Switch,
which can also be connected to a pin of the microcontroller via jumper. The switch is active low
and normally open.
