(1) The leakage current is specified by the digital I/O input leakage.
(2) The analog input voltage range must be within the selected reference voltage range VR+ to VR– for valid conversion results. If the
reference voltage is supplied by an external source or if the internal voltage is used and REFOUT = 1, then decoupling capacitors are
required. See REF, External Reference and REF, Built-In Reference.
(3) The internal reference supply current is not included in current consumption parameter IADC12
