Description
Positive supply for most of the logic function,
including the processor core and most
peripherals.
Ground reference for logic and I/O pins.
Ground reference for logic and I/O pins.
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.

No connect. Leave the pin electrically
unconnected/isolated.
Low drop-out regulator output voltage. This
pin requires an external capacitor between
the pin and GND of 1 µF or greater. The LDO
pin must also be connected to the VDD25 pins
at the board level in addition to the decoupling
capacitor(s).
Positive supply for I/O and some logic.
CPU Mode bit 0. Input must be set to logic 0
(grounded); other encodings reserved.
