Security Vector FSV2

The setting of the Flash Security Vector FSV2 bits [31:0] is responsible for the individual write protection of the 64 Kbytes sectors. It

is only evaluated if write protection bit FSV1 [17] is set.

Note: See section “Flash access in CPU mode” for an overview about the sector organisation of the Flash Memory.

10. Memory Space

The FR family has 4 Gbytes of logical address space (232 addresses) available to the CPU by linear access.

■ Direct addressing area

The following address space area is used for I/O.

This area is called direct addressing area, and the address of an operand can be specified directly in an instruction.

The size of directly addressable area depends on the length of the data being accessed as shown below.

Byte data access: 000H to 0FFH

Half word access: 000H to 1FFH

Word data access: 000H to 3FFH
