• Answer :In Time-Base-Timer, the current from the Avcc pin and that from AVRef pin are the IAH current and IRH current respectively in the data sheet, so power consumption is MAX 5 µA.When the A/D converter is halted, the current value from the Avcc pin and that from AVRef pin are the Avcc current and AVR current respectively, so we believe that power consumption is about tens of nA at room temperature.
