1. When the on-chip reference voltage is used as analog input, first set the ADEX0 bit to 1 (on-chip reference voltage
selected) and then set the VREFMON bit to 1 (on-chip reference voltage and analog input are connected).
When the on-chip reference voltage is not used as analog input, first set the VREFMON bit to 0 (on-chip reference
voltage and analog input are cut off) and then set the ADEX0 bit to 0 (extended analog input pin not selected).
