When detecting a parity error, the receiver in T = 1 mode does not return an error signal. The
transmitter does not sample error signals or repeat the disputed data.
The operation sequence is as follows.
1. When the SIM is not in use, the data line is in the high-impedance state, fixed at high level by
2. The transmitter starts transmission of one frame of data. The data frame begins with the start
3. The SIM then returns the data line to high impedance. The data line is held at high level by the
4. The receiver performs a parity check.
5. If the transmitter does not receive an error signal, it transmits the next frame.

pull-up resistance.
If detecting no parity error and receiving the data normally, the receiver waits for the next
frame, without taking further action.
If a parity error has occurred, the receiver outputs an error signal (DE: low level) for
requesting data repetition in T = 0 mode. After outputting an error signal for the specified
duration, the receiver again sets the signal line to high impedance. The signal line returns to
high level by the pull-up resistance. In T = 1 mode, however, the receiver outputs no error
signal when a parity error occurs.
If the transmitter in T = 0 mode receives an error signal, it repeats the disputed data as in step 2
above. In T = 1 mode, however, the transmitter receives no error signals and performs no
repetition.
