power supply and return pins. QVDD, QVDDx, and QVSS pins are used for internal logic. All other VDD
and VSS pins are for the I/O pads voltage supply, and each pair of VDD and VSS provides power to the
enclosed I/O pads. This design allows different peripheral supply voltage levels in a system.
Because VDDA pins are supply voltages to the analog pads, it is recommended to isolate and noise-filter
the VDDA pins from other VDD pins.
