■ MEMORY SPACE
1.
Memory space
The FR family has 4 Gbytes of logical address space (232 addresses) available to the CPU by linear access.
Direct Addressing Areas
The following address space areas are used as I/O areas.
These areas are called direct addressing areas. The addresses of operands in these areas can be specified
directly within an instruction.
The size of the directly addressable areas depends on the size of the data being accessed as shown below.
→ Byte data access
: 000H to 0FFH
→ Half word data access : 000H to 1FFH
→ Word data access
: 000H to 3FFH

Each mode is set depending on the mode vector fetch after INIT is negated.
The available area of internal RAM is restricted immediately after a reset is released. At least one NOP
instruction is required immediately after overwriting the setting for the available RAM area.
