Section 14 Serial Communication Interface (SCI)
14.7
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.
14.7.1
Figure 14.21 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 V
are both set to 1, closed transmission/reception is possible, enabling self-diagnosis to be carried
out. When the clock generated on the Smart Card interface 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.
