Abstract: A module has switchable operation states. A first switching unit switches the module between a first operation state and a second operation state. A first interface switches between sending signals to another module which has switchable operation states and receiving signals from the other module. The first interface sends a first signal to the other module when the module is in the first operation state, sends a second signal to the other module when the module is to be switched into the second operation state, and receives signals from the other module when the module is in the second operation state. A second interface communicates with the other module. When the second interface receives a response of the other module to the second signal, the first switching unit switches the module into the second operation state. The reliability of module switching is improved in an embodiment.

Abstract translation: 模块具有可切换的操作状态。 第一切换单元在第一操作状态和第二操作状态之间切换模块。 第一接口在发送信号之间切换到具有可切换操作状态的另一个模块，并从另一个模块接收信号。 当模块处于第一操作状态时，第一接口向另一模块发送第一信号，当模块切换到第二操作状态时，向另一个模块发送第二信号，并且当另一个模块接收到来自另一模块的信号时 模块处于第二个操作状态。 第二个接口与另一个模块通信。 当第二接口接收另一个模块对第二信号的响应时，第一切换单元将模块切换到第二操作状态。 在一个实施例中模块切换的可靠性得到改善。
