* ADC is data reg. Right ajusted, can be left by ADLAR in ADMUX
* If left ajusted & no more then 8 bits, read ADCH, otherwise first ADCL
* Conversion:
* Set ADSC (is cleared once conversion is done)
* Or: ADTS mux bits in ADCSRA for auto trigger (will trigger on high)
* interrupt flag will be enabled
