The operating sequence is as follows.
1. When the data line is not in use it is in the high-impedance state, and is fixed high with a pull-
2. The transmitting device starts transfer of one frame of data. The data frame starts with a start
3. With the smart card interface, the data line then returns to the high-impedance state. The data
4. The receiving device carries out a parity check. If there is no parity error and the data is

received normally, the receiving device waits for reception of the next data. If a parity error
occurs, however, the receiving device outputs an error signal (DE, low-level) to request
retransmission of the data. After outputting the error signal for the prescribed length of time,
the receiving device places the signal line in the high-impedance state again. The signal line is
pulled high again by a pull-up resistor.
frame. If it receives an error signal, however, it returns to step 2 and transmits the same data
again.
