All possible P-Flash protection scenarios are shown in Figure 18-14. Although the protection scheme is

loaded from the Flash memory at global address 0x7F_FF0C during the reset sequence, it can be changed

by the user. The P-Flash protection scheme can be used by applications requiring reprogramming in single

chip mode while providing as much protection as possible if reprogramming is not required.
