Internal architecture
The FR family of CPUs has a Harvard architecture in which the instruction bus and data bus are separated.
The 32-bit
16-bit bus converter is connected to the 32-bit bus (F-bus) to provide an interface between the
CPU and peripheral resources.
The Harvard
Princeton bus converter is connected to both of the I-bus and D-bus, providing an interface
between the CPU and the bus controller.
