can anybody explain the definition of Absolute Voltage measurement error in ADC?
Hardware spec displays absolute voltage measurement error is typically 2%.
Is that mean add value has 2% error?
If 16bit adc value is measured as 512 (0x200), then can the measured value have error value of adc 10?
I'd like to know the formula of absolute voltage measurement error.
Thank you.

According to the developers, absolute voltage measurement error is calibrated to the core voltage and is +/- 2%.
Uncalibrated, the value is +/- 5%

I will check with the hardware team for the SOC to see if they know how this value was derived.
