Fuse Bits
2513C–AVR–09/02
Table 98. Lock Bit Protection Modes
Notes:
The ATmega162 has three Fuse bytes. Table 100 and Table 101 describe briefly the
functionality 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.

Memory Lock Bits
1. Program the Fuse bits and Boot Lock bits before programming the LB1 and LB2.
2. “1” means unprogrammed, “0” means programmed
1. See “ATmega161 Compatibility Mode” on page 5 for details.
2. See Table 19 on page 48 for BODLEVEL Fuse decoding.

Protection Type
No restrictions for SPM or 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 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.
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.
