Table 130 Security Set Password Command (F1h)

The Security Set Password command enables 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 next power on reset. When the MASTER password is set by this
command, the master password is registered internally, but 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 specified in
Table 130
on the page 188.
The data transferred controls the function of this command.
