13.3.3
Normal Transfer Mode: Figure 13.3 shows the smart card interface data format in the normal
transfer mode. In reception in this mode, a parity check is carried out on each frame. 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.
