If the contents of the ADCON1, ADMOD, ADINSEL, or OCVREFCR register are written during A/D
conversion, the conversion result is undefined.
When using the A/D converter in 10-bit mode, repeat mode 0, repeat mode 1, or repeat sweep mode, access the
ADi register in 16-bit units. Do not access it in 8-bit units.
