Lock Bits
ATtiny48/88
ATtiny48/88 provide the program and data memory lock bits listed in
Table 20-1.
Notes:
Lock bits can be left unprogrammed (“1”) or can be programmed (“0”) to obtain the additional
features listed in
Table 20-2.
Notes:
Lock bits can be erased to “1” with the Chip Erase command, only.
The ATtiny48/88 has no separate Boot Loader section. The SPM instruction is enabled for the
whole Flash if the SELFPRGEN fuse is programmed (“0”), otherwise it is disabled.
