When the ADuC7060 ADCs are used with more than a single channel (e.g. the multiplexer setting is changed periodically) -- there is a delay of several samples before the output data is settled.
However, there is "An additional time of approximately 60 us per ADC is required before the first ADC is available" - comment for Table 46, page 48, datasheet Rev.C
What is this 60 us? Where is it coming from?
