Abstract
An integrated circuit () includes a firewall input terminal, a first circuit (), and a second circuit (). The firewall input terminal is for receiving a firewall input signal. The first circuit () is coupled to a first power supply voltage terminal () and has an output for providing a control signal. The second circuit is coupled to a second power supply voltage terminal (), to the firewall input terminal (), and to the first circuit (). When the firewall input signal is inactive, an activation of the control signal affects the operation of the second circuit. When the firewall input signal is active, an activation of the control signal does not affect the operation of the second circuit.
