15.7.2
Figure 15.22 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: time for transfer of 1 bit)
• 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
Data transfer with the types of IC cards (direct convention and inverse convention) are performed
as described in the following.
