FSV1 (bit15 to bit0)
The setting of the Flash Security Vector FSV1 bits [15:0] is responsible for the individual write protection of the
8 Kbytes sectors. It is only evaluated if write protection bit FSV1[17] is set.
Explanation of the bits in the Flash Security Vector FSV1 [15:0]
Note : It is mandatory to always set the sector where the Flash Security Vectors FSV1 and FSV2 are located to
write protected (here sector SA4). Otherwise it is possible to overwrite the Security Vector to a setting where
it is possible to either read out the Flash content or manipulate data by writing.
See section “Flash access in CPU mode” on page 37 for an overview about the sector organization of the
Flash Memory.
