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 supply output. A 0.1- F external capacitor should be connected to it.
