Security Bit
The lock bits are implemented using the lowest 16 general-purpose fuse bits. This means that
the 16 lowest general-purpose fuse bits can also be written/erased using the commands for
locking/unlocking regions, see
The security bit allows the entire chip to be locked from external JTAG, aWire, or other debug
access for code security. The security bit can be written by a dedicated command, Set Security
Bit (SSB). Once set, the only way to clear the security bit is through the JTAG
Erase command.
Once the security bit is set, the following Flash Controller commands will be unavailable and
return a lock error if attempted:
One error can be detected in the FSR register after issuing the command:
• Write General-Purpose Fuse Bit (WGPB) to BOOTPROT or EPFL fuses
• Erase General-Purpose Fuse Bit (EGPB) to BOOTPROT or EPFL fuses
• Program General-Purpose Fuse Byte (PGPFB) of fuse byte 2
• Erase All General-Purpose Fuses (EAGPF)
• Programming Error: A bad keyword and/or an invalid command have been written in the
FCMD register.
