Figure 13.22 shows the transfer data format in Smart Card interface mode.
• One frame consists of 8-bit data plus a parity bit in asynchronous mode.
• In transmission, a guard time of at least 2 etu (Elementary time unit: the time for transfer of
• If a parity error is detected during reception, a low error signal level is output for one etu
• If an error signal is sampled during transmission, the same data is retransmitted automatically
