    i need help in designing a circuit using maxq3180(slave) and atmega16(master) to measure power.

    I'm stuck at connecting the selection pin of maxq3180 to atmega16 and i'm not sure how to do that.

    I've read the datasheet of maxq3180 but still unsure, about the unused pin should i leave it unconnected or connect them to GND?
