ADC existencial doubt

After reading the datasheet a few times, I think this might be the easiest:

During conversion, minimum one ADC clock cycle after the trigger event.

If you have a prescaler of 128, then one ADC clock cycle is 8 uS.

So this should work:

ADCSRA |= _BV (ADSC);  // start this conversion
delayMicroseconds (8);

// change MUX channel now (ready for next conversion)
