Internal Architecture
The FR series CPU uses a Harvard architecture with independent instruction bus and data bus. The instruction
bus (I-BUS) is connected to an on-chip instruction cache. a 32-bit
←→
16-bit bus converter is connected to the
bus (F-BUS) to provide an interface between the CPU and peripheral resources. The Harvard

Princeton
bus converter is connected to the both the I-BUS and D-BUS as an interface between the CPU and bus controller.
