Name and Function

A/D

converter

AVCC

Input

Analog power supply: The

reference power supply pin for the

A/D converter.

When the A/D converter is not

used, this pin should be connected

to the system power supply (+5 V

or +3 V).

AVSS

Input

Analog ground: The ground pin for

the A/D converter. This pin should

be connected to the system power

supply (0 V).
