Internal architecture
The FR family CPU uses the Harvard architecture in which the instruction bus and data bus are independent of
each other.
A 32-bit
16-bit bus adapter is connected to the 32-bit bus (D-bus) to provide an interface between the CPU
and peripheral resources.
A Harvard
Princeton bus converter is connected to both the I-bus and D-bus to provide an interface between
the CPU and the bus controller.
The following figure shows the internal architecture structure.
