Program And Data Memory Lock Bits
This section describes how ATtiny13A memories can be programmed.
ATtiny13A provides two lock bits which can be left unprogrammed (“1”) or can be programmed
(“0”) to obtain the additional security listed in
erased to “1” with the Chip Erase command, only.
Program memory can be read out via the debugWIRE interface when the DWEN fuse is pro-
grammed, even if the 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
High-voltage and Serial Programming mode. Fuse bits are
locked in both Serial and High-voltage Programming mode.
debugWire is disabled.
Further programming and verification of the Flash and
EEPROM is disabled in High-voltage and Serial Programming
mode. Fuse bits are locked in both Serial and High-voltage
Programming mode. debugWire is disabled.
