18.3.2
Figure 18.2 shows the pin connection diagram for the smart card interface. During communication
with an IC card, transmission and reception are both carried out over the same data transfer line,
so connect the TxD0 and RxD0 pins on the chip. Pull up the data transfer line to the power supply
V
When using the clock generated by the smart card interface on an IC card, input the SCK0 pin
output to the IC card’s CLK pin. This connection is not necessary when the internal clock is used
on the IC card.
Use the chip’s port output as the reset signal. Apart from these pins, the power and ground pin
connections are usually also required.
Note: When the IC card is not connected and both RE and TE are set to 1, closed communication
18.3.3
Figure 18.3 shows the data format for the smart card interface. In this mode, parity is checked
every frame while receiving and error signals sent to the transmitting side whenever an error is
detected so that data can be re-transmitted. During transmission, error signals are sampled and data
re-transmitted whenever an error signal is detected.
