Section 13 Smart Card Interface

13.1

Overview

SCI supports an IC card (Smart Card) interface conforming to ISO/IEC 7816-3 (Identification

Card) as a serial communication interface extension function.

Switching between the normal serial communication interface and the Smart Card interface is

carried out by means of a register setting.

13.1.1

Features

Features of the Smart Card interface supported by the H8S/2245 are as follows.

• Asynchronous mode

 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

• On-chip baud rate generator allows any bit rate to be selected

• Three interrupt sources

 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 data

transfer controller (DTC) to execute data transfer
