Product and method preventing incorrect storage of data in case of power-down |
摘要 |
The product has a power supply (P2) and a processor (P). The processor (P) has an input (PDD) for receiving a power-down signal indicating a status of the power supply (P2) and another input (Q) connected to another supply. The product also has a non-volatile memory (M) for storing data supplied by the processor (P) and having a device code. The processor (P) has an algorithm to detect a power-down status of the power supply (P2) by repeatedly checking the power-down signal and, upon detection that the power-down signal has a value (S0) corresponding to the power-down status, to complete an ongoing writing operation and stop the storage of data. The processor (P) is adapted for thereafter selecting a device code deviating from the device code of the non-volatile memory (M) to prevent incorrect storage of data. <IMAGE> |
