Section 14 Smart Card Interface

14.1 Overview

An IC card (smart card) interface conforming to the ISO/IEC 7816-3 (Identification Card)

standard is supported as an extension of the serial communication interface (SCI) functions.

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

controlled by a register setting.

14.1.1 Features

Features of the smart card interface supported by the H8/3028 Group are listed below.

â¢ Asynchronous communication

ï£§ Data length: 8 bits

ï£§ Parity bit generation and checking

ï£§ Transmission of error signal (parity error) in receive mode

ï£§ Error signal detection and automatic data retransmission in transmit mode

ï£§ Direct convention and inverse convention both supported

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

â¢ Three interrupt sources

ï£§ There are three interrupt sourcesâtransmit-data-empty, receive-data-full, and

transmit/receive errorâthat can issue requests independently.

ï£§ The transmit-data-empty interrupt and receive-data-full interrupt can activate the DMA

controller (DMAC) to execute data transfer.
