Program And Data Memory Lock Bits
The ATmega88P/168P/328P provides six Lock bits which can be left unprogrammed (“1”) or can
be programmed (“0”) to obtain the additional features listed in
be erased to “1” with the Chip Erase command. The ATmega48P has no separate Boot Loader
section. The SPM instruction is enabled for the whole Flash if the SELFPRGEN fuse is pro-
grammed (“0”), otherwise it is disabled.

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.
