Memory Lock Bits
1477K–AVR–08/10
The ATtiny26 provides two Lock bits which can be left unprogrammed (“1”) or can be pro-
grammed (“0”) to obtain the additional features listed in Table 49. The Lock bits can only be
erased to “1” with the Chip Erase command.

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 Fuse bits are locked in both serial and parallel
programming mode.
