Chapter 2 256 Kbyte Flash Module (FTS256K2V1)
All possible Flash protection scenarios are illustrated in
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.
