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.

Protection Type
No memory lock features enabled.
Further programming of the Flash and EEPROM is disabled in
Parallel and Serial Programming mode. The Fuse bits are locked
in both Serial and Parallel Programming mode.
Further programming and verification of the Flash and EEPROM
is disabled in Parallel and Serial Programming mode. The Boot
Lock bits and Fuse bits are locked in both Serial and Parallel
Programming mode.
