Section 14 Serial Communication Interface (SCI, IrDA, CRC)
14.7
The SCI supports the 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 14.24 shows a sample connection between the smart card and this LSI. As in the figure,
since this LSI communicates with the smart 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 smart card not connected enables closed transmission/reception allowing
self diagnosis. To supply the smart card with the clock pulses generated by the SCI, input the SCK
pin output to the CLK pin of the smart card. A reset signal can be supplied via the output port of
this LSI. (In SCI_5 and SCI-6, the clock generated in SCI cannot be provided to smart cards.)
