Security Lockdown

The security lockdown response activates all the user lock bits to behave as if they are locked. This is irrespective of the underlying user-defined lock state. Any passcodes that were unlocked become immediately locked.

As long as this signal is asserted, the device does not respond to any programming command. The security lockdown response persists until the associated fabric control signal is negated. When the control signal negation happens, lock states return to the user-defined state, but passcodes are locked.
