6. A safety circuit configuration, comprising:
a semiconductor chip, containing:
a first region in which a first group of safety-relevant base functions are implemented in circuitry;
a second region being separated from said first region using technological safety measures and in which a first group of monitoring functions that monitor the safety-relevant base functions being implemented in circuitry; and
a third region, formed on said semiconductor chip and being separated from said first and second regions using the technological safety measures and in which a second group of monitoring functions that monitor the safety-relevant base functions are implemented in circuitry;
at least one safety switch connected to said semiconductor chip; and
an apparatus, selected from the group consisting of a switch and an actuator, connected to said at least one safety switch, wherein the safety circuit configuration is configured to activate or deactivate said apparatus by means of said at least one safety switch, said at least one safety switch being connected to both said first and second groups of monitoring functions and receiving inputs from both said first and second groups of monitoring functions.
