The fusebox read supply is connected to supply of the full speed USBPHY2_VDD. FUSE_VDD is only used for programming.
It is recommended that FUSE_VDD be connected to ground when not being used for programming. See
parameters.
NVCC_DRYICE is a supply output. An external capacitor no less than 4 µF must be connected to it. A 4.7 µF capacitor is
recommended.
