For changing the pull-up resistor, see 4602Specific programming library in Epec Programming and Libraries Manual.
This type of pin is an analog input and a digital input
The configurable features are controlled by three control signals:
The pin can be connected to +5 V by one of three different sizes of pull-up resistors. The three selectable resistor sizes are described in the Electrical characteristics table.

These pins can also be used as digital inputs by using an application library.

Note 1: Temperature and load-dependent, measure using library SensorCalibrationAndDiagnostic. Use pull-up voltage measurement value as the sensor calibration's reference voltage (for more information see Epec Programming and Libraries Manual).
Note 2: Referenced to + 5 V.
Note 3: Exceeding the max value might cause damage to input.
Note 4: When using function ADC_To_Ohm in library ADConversion .
