(1) The leakage current is defined in the leakage current table with P6.x/Ax parameter.
(2) The analog input voltage range must be within the selected reference voltage range V_R+ to V_R– for valid conversion results.
(3) The internal reference supply current is not included in current consumption parameter I_ADC12.
(4) The internal reference current is supplied via terminal V_CC. Consumption is independent of the ADC10ON control bit, unless a
conversion is active. The REFON bit enables the built-in reference to settle before starting an A/D conversion.
(5) Limits verified by design.
