Fuse Bits
2467M–AVR–11/04
Table 116. Lock Bit Protection Modes (Continued)
Notes:
The ATmega128 has three fuse bytes. Table 117 - Table 119 describe briefly the func-
tionality of all the fuses and how they are mapped into the fuse bytes. Note that the
fuses are read as logical zero, “0”, if they are programmed.

Protection Type
No restrictions for SPM or (E)LPM accessing the Boot
Loader section.
SPM is not allowed to write to the Boot Loader section.
SPM is not allowed to write to the Boot Loader section,
and (E)LPM executing from the Application section is not
allowed to read from the Boot Loader section. If interrupt
vectors are placed in the Application section, interrupts
are disabled while executing from the Boot Loader section.
(E)LPM executing from the Application section is not
allowed to read from the Boot Loader section. If interrupt
vectors are placed in the Application section, interrupts
are disabled while executing from the Boot Loader section.
