Section 15 Serial Communication Interface (SCI, IrDA)
15.7
The SCI supports an IC card (Smart Card) interface conforming 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 is carried out by means of a register setting.
15.7.1
Figure 15.21 shows an example of connection with the Smart Card. In communication with an IC
card, since both transmission and reception are carried out on a single data transmission line, the
TxD pin and RxD pin should be connected with the LSI pin. The data transmission line should be
pulled up to the V
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 used by an IC card, the SCK pin output is
input to the CLK pin of the IC card. This LSI port output is used as the reset signal.
