14.7
The SCI supports the IC card (smart card) interface, supporting the ISO/IEC 7816-3
(Identification Card) standard, as an extended serial communication interface function. Smart card
interface mode can be selected using the appropriate register.
14.7.1
Figure 14.21 shows a sample connection between the smart card and this LSI. As in the figure,
since this LSI communicates with the IC card using a single transmission line, interconnect the
TxD and RxD pins and pull up the data transmission line to V
and TE bits to 1 with the IC card not connected enables closed transmission/reception allowing
self diagnosis. To supply the IC card with the clock pulses generated by the SCI, input the SCK
pin output to the CLK pin of the IC card. A reset signal can be supplied via the output port of this
LSI.
