G120 ADC Reference

I want to use a G120 for a new project. Am I able to set the analog reference? I’m not too sure where I need to be looking. Thanks for any help

There is no reference. We recommend internal analog inputs for simple typical needs, like reading battery voltage or temperature for example. For accuracy, a SPI or I2C ADC is recommended.

Gus, is VREFP just tied to 3.3V on the G120? Assuming its not tied to one of the board pins.
