Although this command invalidates the user password, the master password is
retained.

At command issuance (Shadow Block Registers setting contents)
This command erases all user data. This command also invalidates the user
password and releases the lock function.
The host transfers the 512-byte data shown in Table 5.39 to the device. The device
compares the user password or master password in the transferred data with the user
password or master password already set. The device erases user data, invalidates
the user password, and releases the lock function if the passwords are the same.
To recover the master password, issue the SECURITY SET PASSWORD
command and reset the user password.
