Analog Power Supply and Ground Pins (VDDA and VSSA)
VDDA is the power supply pin for the analog circuits of the MCU. It should be decoupled as per the VDD digital supply pin. VSSA is the power supply ground pin for the analog circuits of the MCU. It should be decoupled as per the VSS digital ground pin.
