14.2 Security Protection
QzROM also introduces the concept of Security Protection into FDT. This is optionally set as FDT disconnects,
and prevents further access to the device (Note – once set, this cannot be undone). There are three options:
1. Automatic – FDT will protect the device as it disconnects
2. Prompt – FDT will ask what to do during the disconnect. The default is ‘No’
Figure 14-2 Security Protect message
3. None – FDT will not protect the device on disconnect
As the disconnect actually happens the result of the operation will be echoed to the Output window. There are
several ways of changing this setting depending on the current mode of operation:
14.2.1 Toolbar
In full FDT mode and with a QzROM based project the QzROM toolbar will be enabled. This shows the
currently chosen option, which can be changed by simply clicking on an adjoining icon.

Figure 14-4 Prompt
Figure 14-5 None
Note – clicking on the icons will not immediately protect the device. This is still merely the current disconnect
setting.
14.2.2 Project
It is also possible to change this option from the project properties dialog, as well as viewing the current setting.
This is done from the Programmer tab:
