Input Analog input pins
AVCC 76 76 P15 Input
Analog power supply pins. When
the A/D converter is not used,
these pins should be connected to
the system power supply (+3.3 V).
AVref 77  N14 Input
Analog reference voltage input pin.
When the A/D converter is not
used, this pin should be connected
to the system power supply (+3.3
V).
AVSS 67 67 P12 Input
Analog ground pins. These pins
should be connected to the system
power supply (0 V).
