15.4.1
The primary functions of the smart card interface are described below.
1. Each frame consists of 8-bit data and a parity bit.
2. During transmission, the card leaves a guard time of at least 2 etu (elementary time units: the
3. During reception, the card outputs an error signal low level for 1 etu after 10.5 etu has elapsed
4. During transmission, it automatically transmits the same data after allowing at least 2 etu from
5. Only start-stop type asynchronous communication functions are supported; no synchronous
15.4.2
Figure 15.2 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 TxD and RxD 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 SCK 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
