13.7
The SCI supports an IC card (Smart Card) interface that conforms to ISO/IEC 7816-3
(Identification Card) as a serial communication interface extension function. Switching between
the normal serial communication interface and the Smart Card interface mode is carried out by
means of a register setting.
13.7.1
Figure 13.21 shows an example of connection with the Smart Card. In communication with an IC
card, as both transmission and reception are carried out on a single data transmission line, the TxD
pin and RxD pin should be connected to the LSI pin. The data transmission line should be pulled
up to the power supply (other than channel 2: P2Vcc, channel 2: P1Vcc) with a resistor. If an IC
card is not connected, and the TE and RE bits are both set to 1, closed transmission/reception is
possible, enabling self-diagnosis to be carried out. When the clock generated on the SCI is
supplied to an IC card, the SCK pin output is input to the CLK pin of the IC card. When an
internal clock is used in an IC card, this connection is not necessary. This LSI port output is used
as the reset signal. Adding to these connections, connection of pins with power supply and ground
is necessary.
