During A/D conversion 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 the RA3/AN3/VREF+ pin or VDD, whichever is selected as the VREFH source. VREFL current is from
the RA2/AN2/VREF-/CVREF pin or VSS, whichever is selected as the VREFL source.
