The ground reference for the analog circuits (ADC, 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.
Low drop-out regulator output voltage. This pin requires an
external capacitor between the pin and GND of 1 µF or
greater. When the on-chip LDO is used to provide power to
the logic, the LDO pin must also be connected to the VDD25
pins at the board level in addition to the decoupling
capacitor(s).
No connect. Leave the pin electrically unconnected/isolated.
