Pin Connections

An example of pin connections for the smart card interface is shown in figure 30.11.

In communication with the smart card, transmission and reception are performed using a single

data transmit line. The data transmit line should be pulled up by a resistance on the power supply

cc side.

When using the clock generated by the smart card interface with the IC card, the SIM_CLK pin

output is input to the CLK pin of the IC card. If an internal clock of the IC card is used, this

connection is not needed.

Note:

The transmission/reception in loop can perform self-check when the RE and TE bits are

set to 1 without connecting to the IC card.
