| 摘要 |
The invention concerns a microcircuit (40) comprising an interface circuit (1) for sensing low level commands received in the form of electrical signals or combinations of electric signals applied to electrical contacts (RST, IO, CLK). The invention is characterised in that the microcircuit comprises means (12) for converting at least one first low level command into a bit of value 0 and at least one second low level command into a bit of value 1, so as to deliver a bit string (DTin1) on receiving a series of said first and second low level commands. The invention is applicable to binary data transmission to memory cards via an ISO 7816-2 low level communication interface. |
