All possible P-Flash protection scenarios are shown in
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.
