2.6.2 VDD - Core Power Pin
This 2.5v supply is derived from the internal voltage regulator. There is no static load on this pin allowed.
The internal voltage regulator is turned off if VREGEN is tied to ground. In that case, VDD must be
supplied externally with 2.5v.
2.6.3 VDDX, VSSX - Power & Ground Pins for I/O Drivers
External power and ground for I/O drivers of Ports B, A, U, S and R.
2.6.4 VDD3X, VSS3X - Power & Ground Pins for I/O Drivers
External power and ground for I/O drivers of Ports Q, P, M, J and T.
2.6.5 VDDA, VSSA, VSSA1 - USB PHY Power Pins
VDDA is 3.3v output for connecting USB pull-up resistor (RPU).
VSSA and VSSA1 are ground of USB PHY, which generates the 480bps USB signals. VSSA should also
be used for ground of Pierce oscillator crystal.
