Once the correct Password has been provided, the Lock-Down bit is cleared and the Non-
Volatile Modify Protection bits can be set or reset using the appropriate commands (the Set
Non-Volatile Modify Protection Bit command or the Clear Non-Volatile Modify Protection Bits
command, respectively).
If the Password provided is not correct, the Lock-Down bit remains locked and the state of the
Non-Volatile Modify Protection bits cannot be modified.
The Password is a 64-bit code located in the memory space. It must be programmed by the
user prior to selecting the Password Protection mode. The Password is programmed by issuing
a Password Program command and checked by issuing a Password Verify command. The
Password should be unique for each part.
Once the device is in Password Protection mode, the Password can no longer be read or
retrieved. Moreover, all commands to the address where the password is stored, are disabled.
Refer to
Table 10: Block Protection Status
and
Figure 7: Software Protection Scheme
