2.4.4 Flash Security
2.4.4.1
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
2.4.4.2
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.
V 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.
