Figure 14-3 shows the Smart Card interface data format. In reception in this mode, a parity check
is carried out on each frame, and if an error is detected an error signal is sent back to the
transmitting end, and retransmission of the data is requested. If an error signal is sampled during
transmission, the same data is retransmitted.
