All possible Flash protection scenarios are shown in Figure 29-9. Although the protection scheme is
loaded from the Flash array at global address 0x7F_FF0D during the reset sequence, 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.
