(1) The analog input voltage range must be within the selected reference voltage range V_R+ to V_R- for valid conversion results.
(2) The internal reference supply current is not included in current consumption parameter I(ADC14).
(3) VeREF- pin should be connected to onboard ground for ADC14VRSEL = 1110.
