Negative Analog Input Channel 1
Positive Analog Input Channel 1
ADC1 Buffered Reference Voltage. Bypass REF1 with a 1μF capacitor to AGND.
Reference Voltage Output/Input. Reference voltage for analog-to-digital conversion. In internal reference
mode, the reference buffer provides a +2.5V nominal output. In external reference mode, overdrive REFIO
with an external reference between 2.3V to 2.7V. Bypass REFIO with a 1μF capacitor to AGND.
