ABSTRACT:
The device includes a parent microcontroller in a bond-out version and a derivative microcontroller in a non-bond-out version, in order to emulate the derivative microcontroller. To this end, the parent microcontroller is connected to an external program memory by means of memory connection pins. The derivative microcontroller comprises an additional functional processing facility, an internal program memory and a processor element. Upon emulation the derivative microcontroller receives an emulation control signal. Communication means between the processor and the internal program memory on the one side and the additional functional process facility on the other side are thus deactivated. Finally, the two microcontrollers are interconnected and connected to an external program memory in such a manner that a series of standard pins and the processor of the parent microcontroller are activated, and the external processing section of the derivative microcontroller and said external program memory are activated.
