Description
No connect. Leave the pin electrically
unconnected/isolated.
No connect. Leave the pin electrically
unconnected/isolated.

Positive supply for I/O and some logic.
Ground reference for logic and I/O pins.
VCC of the Ethernet PHY
VCC of the Ethernet PHY
GND of the Ethernet PHY
GND of the Ethernet PHY
Ground reference for logic and I/O pins.
Positive supply for most of the logic function,
including the processor core and most
peripherals.

GPIO port B bit 6
Analog comparator 0 positive input
GPIO port B bit 5

Positive supply for I/O and some logic.
Ground reference for logic and I/O pins.
GPIO port D bit 4
GPIO port D bit 5
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.
