Memory Programming
Atmel ATA6612/ATA6613
Program And Data Memory Lock Bits
The Atmel
or can be programmed (“0”) to obtain the additional features listed in
bits can only be erased to “1” with the Chip Erase command. The SPM instruction is enabled
for the whole Flash if the SELFPRGEN fuse is programmed (“0”), otherwise it is disabled.
