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 (1 etu in block transfer mode) (elementary time
• 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 synchronous communication
unit: the time for transfer of 1 bit) is left between the end of the parity bit and the start of the
next frame.
period, 10.5 etu after the start bit. (This does not apply to block transfer mode.)
