■ MEMORY SPACE
1.
Memory space
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 length 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
