Note: 1 For 5V applications, VDD must be connected to a 5.0V source. For 3.3V applications, VDD

must be connected to a 3.3V source.

2 These signals can be used on one of two different ports (Port 1 or Port 4) for flexibility.

Default is Port1.

3 AVREF and 3.3V AVCC are shared in the 52-pin package only. ADC channels must use 3.3V

as AVREF for the 52-pin package.
