Methods and apparatus for creating microcode-implemented peripheral devices for a microcontroller core formed in a monolithic integrated circuit. The microcontroller core has a control store for storing microcode instructions; execution circuitry operable to execute microcode instructions from the control store; and means for loading a suite of one or more microcode-device modules defining an optional peripheral device, the optional peripheral device being implemented by microcode instructions executed by the execution circuitry in accordance with the definition provided by the microcode-device modules. <IMAGE> |
