■ CPU CORE
1.
Memory Space
The FR family has a logical address space of 4 Gbytes (232 bytes) and the CPU linearly accesses the memory
space.
Direct addressing area
The following area in the address space is used for I/O.
This area is called direct addressing area and an operand address can be specified directly in an instruction.
The direct addressing area varies with the data size to be accessed as follows :
