31.2 Fuse Bits
8266A-MCU Wireless-12/09
The ATmega128RFA1 has three Fuse bytes.
466 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.

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.
