AN7 to AN0 75 to 68 Input Analog input pins
AVCC 76 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 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).
A/D converter
AVSS 67 Input
Analog ground pin. This pin should be
connected to the system power supply (0
V).
ADTRG 43 Input
External trigger input pin to start A/D
conversion
