Input Analog input pins
AVCC J10 Input
Analog power supply pins for the A/D converter
and D/A converter. When the A/D converter and
D/A converter are not used, these pins should be
connected to the system power supply (+3.3 V).
AVref J11 Input
Reference voltage input pin for the A/D converter
and D/A converter. When the A/D converter and
D/A converter are not used, this pin should be
connected to the system power supply (+3.3 V).
AVSS H7 Input
Ground pins for the A/D converter and D/A
converter. These pins should be connected to the
system power supply (0 V).
