跟據你的資料,有找到原廠 FAQ 說明了~

So, when you perform a chip erase on your AVR, all the Lock Bits will become unprogrammed (reset), and you will be able to re-program your AVR for a firmware update. After the firmware upgrade is done, you can secure your firmware against external inspection by programming the Lock Bits again.
Since re-programming of a secured AVR relies on a complete chip-erase, it may be an idea to program the EESAVE fuse (EEPROM memory is preserved through the Chip Erase) before the Lock Bits is programmed, if you are using the EEPROM memory for permanent data storage.
會先上原來的試一遍看看~
