Name, Function & Alternate Function

Ground: 0V reference

Analog Ground: 0V reference for analog part

Power Supply:

Analog Power Supply: This is the power supply voltage for analog

part

For a normal use this pin must be connected.

Analog Reference : reference for analog converter . This is the

reference voltage of the A/D converter. As output, can be used by

external analog
