ABSTRACT:
A reset arrangement for a microcontroller and/or further hardware circuits to be reset should be optimally adaptable to the requirements of the microcontroller and/or the hardware circuits. To this end, the reset arrangement is formed in such a way that it is capable of applying a reset signal to the microcontroller via a reset line, supplies a first reset signal upon a system cold start of the reset arrangement and the microcontroller, the duration of this first reset signal being chosen to be such that any provided type of microcontroller starts reliably, is programmed with a second reset signal after a system cold start of the microcontroller, the duration of this second reset signal being adapted to the requirements of the microcontroller, and supplies the second, programmed reset signal as a reset signal at subsequent cold or hot starts.
