AD0SEL=ADCN_0_PIN
A/D Input Select Register: Selects between external pin and internal source for various channels
AD0SEL | This field selects the input source for channel 0. All other values are reserved. 0 (ADCN_0_PIN): ADCn_0 pin. Voltage on ADC channel 0 input. 1 (CORE_VOLTAGE_REGULAT): Core voltage regulator output (1.2V to 1.8V). If the WRAPEN field is 0x2, the core voltage regulator output is also is output on the ADC0/1_0 pin. 2 (INTERNAL_VOLTAGE_REF): Internal voltage reference. If the WRAPEN field is 0x2, the internal voltage reference is also is output on the ADCn_0 pin. 3 (TEMPERATURE_SENSOR): Temperature Sensor. If the WRAPEN field is 0x2, the temperature sensor voltage is also is output on the ADCn_0 pin. 4 (VDDADIV2): VDDA/2. 15 (NO_CONNECTION_OR_LOA): No connection or load |
