(on-chip reference voltage selected) and then set the OCVREFAN 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 OCVREFAN 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).
Set the PRC3 bit in the PRCR register to 1 (write enabled) before rewriting the OCVREFCR register.
If the content of the OCVREFCR register is rewritten during A/D conversion, the conversion result is
undefined.
