Hi

You can put the vref 1.2v on an ADC input pin. But it need to be connected from outside of the MCU, due to the vref 1.2v is not on the list of "3.7.1.3 ADCx Connections/Channel Assignment" in K02P64M100SFARM).

The ADC input voltage must not higher than the voltage of ADC reference. See the "3.6.1.1 16-bit ADC operating conditions" in K02P64M100SFA.

Best Regards,

Robin
