No connect. Leave the pin electrically unconnected/isolated.
Power
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.
TTL
GPIO port B bit 4.
Analog Analog comparator 0 negative input.
