• Bit 3:2 - BLBAT[1:0]: Boot Lock Bit Application Table Section
These bits indicate the locking mode for the Application Table Section. Even though the BLBAT
bits are writable, they can only be written to a stricter locking. Resetting the BLBAT bits is only
possible by executing a Chip Erase Command.
Table 4-10.
• Bit 1:0 - LB[1:0]: Lock Bits
These bits indicate the locking mode for the Flash and EEPROM in Programming Mode. These
bits are writable only through an external programming interface. Resetting the Lock Bits is only
possible by executing a Chip Erase Command.
Table 4-11.

Description
No Lock, no restrictions for SPM and (E)LPM accessing
the Application Table Section.
Write Lock, SPM is not allowed to write the Application
Table
Read Lock, (E)LPM executing from the Boot Loader
Section is not allowed to read from the Application Table
Section.
If the interrupt vectors are placed in the Boot Loader
Section, interrupts are disabled while executing from the
Application Section.
Read and Write Lock, SPM is not allowed to write to the
Application Table Section and (E)LPM executing from
the Boot Loader Section is not allowed to read from the
Application Table Section.
If the interrupt vectors are placed in the Boot Loader
Section, interrupts are disabled while executing from the
Application Section.
Description
No Lock, no memory locks enabled.
Write lock, programming of the Flash and EEPROM is
disabled for the programming interface. Fuse bits are
locked for write from the programming interface.
Read and Write Lock, programming and
read/verification of the flash and EEPROM is disabled
for the programming interface. The lock bits and fuses
are locked for read and write from the programming
interface.
