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.
