The main functions of the Smart Card interface are as follows.
• One frame consists of 8-bit data plus a parity bit.
• 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 the error signal is sampled during transmission, the same data is transmitted automatically
• Only asynchronous communication is supported; there is no clocked synchronous
