Program And Data Memory Lock Bits
This section describes the different methods for Programming the ATtiny25/45/85 memories.
ATtiny25/45/85 provides two Lock bits which can be left unprogrammed (“1”) or can be pro-
grammed (“0”) to obtain the additional security listed in
“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).
Table 20-1.
Note:
Table 20-2.
Notes:
Lock bits can also be read by device firmware. See section
