RADIO WITH OPTIONS BOARD ABSTRACT OF THE DISCLOSURE: A FM mobile radio is disclosed which is capable of future functional expansion due to a unique microprocessor hardware/software control system. The radio includes a control microprocessor which is capable of performing all the basic radio control functions. In addition, options are added via a plug-on board that includes an option microprocessor which interfaces with the control microprocessor over a data bus and with the radio's audio circuits through audio processing circuitry. The software of the system allows control to be passed to the option board. The radio operates in a standard control mode and an option control mode. In the standard mode, in which no option board is present, the control processor performs all basic radio control functions. In the option mode, where the option control microprocessor is present, the main control processor typically receives commands from the option board.
