Abstract
An apparatus for communication using a master-slave communication protocol includes a master circuit and a slave circuit configured to communicate with each other using a master-slave communication protocol. The apparatus also includes an interface circuit coupled to the master and slave circuits. In response to a first control signal having a first value, the interface circuit forwards messages received from the master circuit to the slave circuit and forwards responses received from the slave circuit to the master circuit. In response to the first control signal having a second value, the interface circuit prevents messages received from the master circuit from being forwarded from the master circuit to the slave circuit.
