Abstract

A control device has a microcomputer, a memory which has a control program and can be cleared and programmed electrically, a read-only memory and a serial interface. In the read-only memory, a program for reprogramming the memory which can be cleared and programmed electrically is stored. For the reprogramming of the memory which can be cleared and programmed electrically, the control device receives the data to be programmed from an external communication device via the serial interface. The control device causes the program for reprogramming the memory which can be cleared and programmed electrically to be processed without the control program having to be started or operative for this purpose.
