thus allowing them to be connected to a 3.3V microcontroller or other external logic. It is
also possible to have one IO interface channel driving out at 5V level, and the other at
3.3V level. In this case one of the VCCIOx pins would be connected to 5V, and the other
connected to 3.3V.
A USB self-powered design uses its own power supplies, and does not draw any of its
power from the USB bus. In such cases, no special care need be taken to meet the USB
suspend current (0.5 mA) as the device does not get it’s power from the USB port.
Note that if the SI/WUx pins are not being used they should be pulled up to the same
supply as their respective VCCIOx pin.
