What´s the settling time of de A/D's Mux in ADuC7020, i.e. how long should be the minimum time delay between a channel selection (e.g. issuing an ADCCP in a single-ended configuration) and start a conversion?
Basically if you follow the recommendations in the datasheet (page 44 - 46) related to the input impedance and providing signals to the ADC, than there is no switching time required. Because the default acquisition time of the ADC, as explained on page 42 in the datasheet, is sufficient to achieve specified performance.
