    • The electronic chip (10) comprises an interface (11) enabling it to communicate with a terminal and a processing circuit (13) capable of performing processing when the chip communicates with the terminal. A time base circuit (18) is connected to the processing circuit (13) for generating a first signal (SI) during at least one given moment if processing has not yet been completed at said moment. A restart signal (SR) is transmitted to the interface in response to the first signal with the purpose of indicating to the terminal that the chip is still operating.
    • 电子芯片(10)包括能够与终端通信的接口(11)和能够在芯片与终端通信时能够执行处理的处理电路(13)。 时基电路(18)连接到处理电路(13),用于在至少一个给定时刻产生第一信号(SI),如果处理尚未在所述时刻完成。 响应于第一信号,重新启动信号(SR)被发送到接口,目的是向终端指示芯片仍在运行。
