The AT49BV160S(T) device also contains a freeze feature that will freeze the lock status of the
secure regions. The freeze feature prevents any further locking of the secure regions. If the user
requires certain regions to be locked, then these regions must be programmed and locked prior
to activation of the freeze command. It is important to note that enabling the freeze feature is
irreversible.
