Abstract
The electronic chip ( ) comprises an interface ( ) enabling it to communicate with a terminal and a processing circuit ( ) capable of performing processing when the chip communicates with the terminal. A time base circuit ( ) is connected to the processing circuit ( ) 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.
