Notes:
The ATmega169A/169PA/329A/329PA/3290A/3290PA/649A/649P/6490A/6490P has three
Fuse bytes.
they are mapped into the Fuse bytes. Note that the fuses are read as logical zero, “0”, if they are
programmed.

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
