Program and Data Memory Lock Bits
Fuse Bits
The ATtiny87/167 provides two Lock bits which can be left unprogrammed (“1”) or can be pro-
grammed (“0”) to obtain the additional features listed in
erased to “1” with the Chip Erase command. The ATtiny87/167 has no separate Boot Loader
section.

Note:
Table 21-2.
Notes:
The ATtiny87/167 has three Fuse bytes.
the functionality of all the fuses and how they are mapped into the Fuse bytes.
The SPM instruction is enabled for the whole Flash if the SELFPRGEN fuse is programmed
(“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 Fuse
bits are locked in both Serial and Parallel Programming mode.
