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 H8/3067 Group 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.
 The transmit-data-empty interrupt and receive-data-full interrupt can activate the DMA
controller (DMAC) to execute data transfer.
