All possible Flash protection scenarios are shown in
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.

Flash Protection Lower Address Range Disable — The FPLDIS bit determines whether there is a
protected/unprotected area in a specific region of the Flash memory beginning with global address 0x7F_8000.
0 Protection/Unprotection enabled.
1 Protection/Unprotection disabled.
Flash Protection Lower Address Size — The FPLS[1:0] bits determine the size of the protected/unprotected
