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, in which the address of an operand can be specified directly
during an instruction.
The size of directly addressable areas depends on the data size to be being accessed as follows.
→ byte data access
: 000-0FFH
→ half word data access
: 000-1FFH
→ word data access
: 000-3FFH
