Chapter 55 Flash Security
3.Flash Security Vectors
3.3 Security Vector FSV2
The setting of the Flash Security Vector FSV2 bits [31:0] is responsible for the individual write protection of the
64 kByte sectors. It is only evaluated if write protection bit FSV1[17] is set.
Explanation of the bits in the Flash Security Vector FSV2[31:0] (valid for MB91F467DA):
Remark: The content of the security vector FSV2[31:0] depends on the size and the data width configuration
of the embedded flash memory. Therefore always check the appropriate datasheet if the data shown here are
valid for the product you are using.
See Chapter 54 Flash Memory (Page No.993) for an overview about the sector organisation of the Flash
Memory.
