ADVANCE INFORMATION
The ADC inputs should be kept below VDDA + 0.3 V. If an ADC input goes above this level, ADC disturbances to other channels may occur by two mechanisms:
The VREFHI pin must be kept below VDDA + 0.3 V to ensure proper functional operation. If the VREFHI pin exceeds this level, a blocking circuit may activate, and the internal value of VREFHI may float to 0 V internally, giving improper ADC conversion.
