All possible Flash protection scenarios are illustrated in Figure 2-8. Although the protection scheme is
loaded from the Flash array after reset, it can be changed by the user. This protection scheme can be used
by applications requiring re-programming in single-chip mode while providing as much protection as
possible if re-programming is not required.
