Buffer Type^a Description
Power Ground reference for logic and I/O pins.
Power
OD
OD
OD
OD
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.
An output that indicates the processor is in
Hibernate mode.
I²C module 0 clock.
I²C module 0 data.
I²C module 1 clock.
OD
I²C module 1 data.

-
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 VDDC pins at the board level in
addition to the decoupling capacitor(s).
No connect. Leave the pin electrically
unconnected/isolated.
