Buffer Type^a Description
Power Ground reference for logic and I/O pins.

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.

TTL
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).
Non-maskable interrupt.
Main oscillator crystal input or an external clock
reference input.
Main oscillator crystal output. Leave unconnected
when using a single-ended clock source.
