Abstract
The present invention relates to a security control comprising a first controller having a first clock generator for generating a first clock signal, a separate second controller having a second clock generator for generating a second clock signal, wherein the first clock signal is output to a first input of the first controller and to a first input of the second controller, and the second clock signal is output to a second input of the first controller and to a second input of the second controller. In addition, the present invention relates to a method for operating a security control.
Claims12
A control device, comprising:
- a first controller comprising a first processor having a first clock generator for generating a first clock signal;
- a separate second controller comprising a second processor having a second clock generator for generating a second clock signal,
- wherein the first clock signal is output to a first input of the first controller and to a first input of the second controller, the first clock signal triggering an interrupt in the first controller and the second controller, and
- wherein the second clock signal is output to a second input of the first controller and to a second input of the second controller.
A method for operating a security control comprising a first controller comprising a first processor having a first clock generator M and a separate second controller comprising a second processor having a second clock generator, the method comprising:
- generating a first clock signal by the first clock generator;
- generating a second clock signal independent of the first clock signal by the second clock generator;
- outputting the first clock signal to a first input of the first controller and to a first input of the second controller, the first clock signal triggering an interrupt in the first controller and the second controller;
- and
- outputting the second clock signal to a second input of the first controller and to a second input of the second controller.
