Note: A loop-back test can be performed by setting both RE and TE to 1 without connecting a
14.3.3
Figure 14.3 shows the data format of the smart card interface. In receive mode, parity is checked
once per frame. If a parity error is detected, an error signal is returned to the transmitting device to
request retransmission. In transmit mode, the error signal is sampled and the same data is
retransmitted if the error signal is low.
