Voltage Measurement

V_DDIOx supply voltage is available as an internal input channel to the ADC. The voltage is divided by ten to allow the use of any internal ADC reference. To measure V_DDIOx/10, the user is recommended to follow these steps:

1. 1.Configure the voltage reference for the ADC.
2. 2.Select V_DDIOx/10 as the positive input to the ADC.
3. 3.Run a single-ended ADC conversion.
4. 4.Calculate the voltage using the following equation:
   VDDIOx=ADC Result×VREF×10ADC Resolution
