Program And Data Memory Lock Bits
ATtiny2313A/4313
This section describes the different methods for programming ATtiny2313A/4313 memories.
The ATtiny2313A/4313 provides two Lock bits which can be left unprogrammed (“1”) or can be
programmed (“0”) to obtain the additional features listed in
erased to “1” with the Chip Erase command.
Program memory can be read out via the debugWIRE interface when the DWEN fuse is pro-
grammed, even if lock bits are set. Thus, when lock bit security is required, debugWIRE should
always be disabled by clearing the DWEN fuse.

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.
