ABSTRACT:
A circuit arrangement for executing a reset, in which controlled resetting of a functional computer and a safety module takes place. A reset stage is able to coerce both the functional computer and the safety module into a reset state, while all output stages are switched off for all reset states. The functional computer and the safety module are connected by a serial interface to continually monitor each other and can mutually reset one another in the case of a fault.
