Power supply for the A/D converter. Connect this

pin as close as possible to the VCC pin and at the

same voltage as VCC. If the power supply voltage

to be used for the A/D converter is not equal to

VCC, connect a 0.1-µF bypass capacitor between

the AVCC and AVSS pins. (However, this is not

necessary when the AVCC pin is directly connected

to the VCC pin.)

Ground for the A/D converter. Connect this pin as

close as possible to GND at the same voltage as

GND.
