The operating sequence is:
1. The data line is high impedance when not in use and is fixed high with a pull-up resistor.
2. The transmitting side starts one frame of data transmission. The data frame starts with a start
3. On the smart card interface, the data line returns to high impedance after this. The data line is
4. The receiving side checks parity. When the data is received normally with no parity errors, the
5. The transmitting side transmits the next frame of data unless it receives an error signal. If it

Table 14.3 shows the bit map of the registers that the smart card interface uses. Bits shown as 1 or
0 must be set to the indicated value. The settings for the other bits are described below.

receiving side then waits to receive the next data. When a parity error occurs, the receiving
side outputs an error signal (DE, low level) and requests re-transfer of data. The receiving
station returns the signal line to high impedance after outputting the error signal for a specified
period. The signal line is pulled high with a pull-up resistor.
