Figure 15.22 shows the data transfer formats in smart card interface mode.
• One frame contains 8-bit data and a parity bit in asynchronous mode.
• During transmission, at least 2 etu (elementary time unit: time required for transferring one bit)
• If a parity error is detected during reception, a low error signal is output for 1 etu after 10.5 etu
• If an error signal is sampled during transmission, the same data is automatically re-transmitted
For communication with the IC cards of the direct convention and inverse convention types,
follow the procedure below.
