How to Read This Manual ■ Description Format of this Manual Major terms used in this manual are explained below: Term Meaning I-BUS 16-bit wide bus used for internal instructions. Since the FR series uses an internal Harvard architecture, independent buses are used for instructions and data. A bus converter is connected to the I-BUS. D-BUS Internal 32-bit wide data bus. Internal resources are connected to the D-BUS. C-BUS Internal multiplex bus. The C-BUS is connected to the I-BUS and D-
