XMEGA A
The Lock bits are used to set protection level on the different flash sections. They are used to
block read and/or write access of the code. Lock bits can be written from en external program-
mer and from the application software to set a more strict protection level, but not to set a less
strict protection level. Chip erase is the only way to erase the lock bits. The lock bits are erased
after the rest of the flash memory is erased.
An unprogrammed fuse or lock bit will have the value one, while a programmed flash or lock bit
will have the value zero.
Both fuses and lock bits are reprogrammable like the Flash Program memory.
