Flash Security
6.1.
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
6.2.
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 Kbytes sectors.
6.2.1.
FSV1 (bit31 to bit16)
The setting of the Flash Security Vector FSV1 bits [31:16] is responsible for the read and write protection modes.
