Figure 111. Security Set Password command (F1h)
The Security Set Password command enables the security mode feature (device lock function) and sets
the master password or the user password.
The security mode feature (device lock function) is enabled by this command and the device is not locked
immediately. The device is locked after the next power on reset or hard reset. When the MASTER pass-
word is set by this command, the master password is registered internally. The device is NOT locked after
next power on reset or hard reset.
This command requests a transfer of a single sector of data from the host including the information speci-
fied in Figure 112 on page 154.
The data transferred controls the function of this command.
