The SCI supports an IC card (smart card) interface handling ISO/IEC7816-3 (Identification Card)

character transmission as a serial communication interface expansion function.

Switchover between the normal serial communication interface and the smart card interface is

controlled by a register setting.

Features of the smart card interface supported by the H8/3062 Series are listed below.

• Asynchronous communication

 Data length: 8 bits

 Parity bit generation and checking

 Transmission of error signal (parity error) in receive mode

 Error signal detection and automatic data retransmission in transmit mode

 Direct convention and inverse convention both supported

• Built-in baud rate generator allows any bit rate to be selected

• Three interrupt sources

 There are three interrupt sources—transmit-data-empty, receive-data-full, and

transmit/receive error—that can issue requests independently.
