Default Fuse Value
Flash Memory Parameters
The devices are shipped with the FGPFRLO register value: 0xFC07FFFF:
See also the AT32UC3B Bootloader user guide document.
After the JTAG chip erase command, the FGPFRLO register value is 0xFFFFFFFF.
The bootloader uses one word in the flash User page to store its configuration. This configura-
tion word is located at address 0x808001FC and its default value is 0x929E0D6B.
Refer to the bootloader documentation for more information.
Each device has a unique 120 bits serial number readable from address 0x80800204 to
0x80800212.
• GPF31 fuse set to 1b. This fuse is used by the pre-programmed USB bootloader.
• GPF30 fuse set to 1b. This fuse is used by the pre-programmed USB bootloader.
• GPF29 fuse set to 1b. This fuse is used by the pre-programmed USB bootloader.
• BODEN fuses set to 11b. BOD is disabled.
• BODHYST fuse set to 1b. The BOD hysteresis is enabled.
• BODLEVEL fuses set to 000000b. This is the minimum voltage trigger level. BOD will never
• BOOTPROT fuses set to 011b. The bootloader protected size is 8 Ko.
