Note that the general-purpose fuse bits 29 to 31 are meaningless for the MCU hardware. They
are only interpreted by the bootloader and can be freely used by the application if the bootloader
is removed.

With ISP, use the
‘Program Fuses...’ on the appropriate ISP AVR32 target in AVR32 Studio (see Section
7.5.2).
From the running embedded application, use the WGPB, EGPB, PGPFB and EAGPF
FLASHC commands. See the AVR UC3 datasheets referred to by Section 3 for further
information and take care of the Lock errors that can occur with these commands.
