cycle.
Note 1:
The A/D conversion result never decreases with an increase in the input voltage and has no missing
codes.
2:
VREFH current is from RA3/AN3/VREF+ pin or VDD, whichever is selected as the VREFH source.
VREFL current is from RA2/AN2/VREF-/CVREF pin or VSS, whichever is selected as the VREFL source.
