Power Positive supply for I/O and some logic.
Power Ground reference for logic and I/O pins.
Analog Analog-to-digital converter input 7.
Analog Analog-to-digital converter input 6.
Power
The ground reference for the analog circuits
(ADC, Analog Comparators, etc.). These are
separated from GND to minimize the electrical
noise contained on VDD from affecting the
analog functions.
Power
The positive supply (3.3 V) for the analog
circuits (ADC, Analog Comparators, etc.).
These are separated from VDD to minimize
the electrical noise contained on VDD from
affecting the analog functions.
Analog Analog-to-digital converter input 5.
Analog Analog-to-digital converter input 4.
