发明名称 Electronic chip for a portable object
摘要 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.
