Note 1:
AN24 (EXTREF) is an internal analog input. To measure the voltage at AN24 (EXTREF), an analog comparator must be enabled
and EXTREF must be selected as the comparator reference.
and EXTREF must be selected as the comparator reference.
2:
AN25 (INTREF) is an internal analog input and is not available on a pin.
