3.1 Vector addresses

Two Flash Security Vectors (FSV1, FSV2) are located parallel to the Boot Security Vectors (BSV1, BSV2)
controlling the protection functions of the flash security module:

FSV1: 0x14:8000 BSV1: 0x14:8004
FSV2: 0x14:8008 BSV2: 0x14:800C

Remark: The addresses of both boot security vectors and flash security vectors depend on the size and the
data width configuration of the embedded flash memory. Therefore always check the appropriate datasheet if
the addresses shown here are valid for the product you are using.

3.2 Security Vector FSV1

The setting of the Flash Security Vector FSV1 is responsible for the read and write protection modes and the
individual write protection of the 8 kByte sectors.

FSV1 (bits 31 to 16)

The setting of the Flash Security Vector FSV1 bits [31:16] is responsible for the read and write protection
modes.
