Section 16 Smart Card Interface

16.1 Overview

As an added serial communications interface function, the SCI supports an IC card (smart card)

interface that conforms to the ISO/IEC7816-3 (Identification Card) data transmission protocol

format T = 0 (asynchronous full-duplex character transmission protocol). Register settings are

used to switch between the normal serial communication interface and the smart card interface.

16.1.1 Features

The smart card interface has the following features:

â¢ Asynchronous mode

ï£§ Data length: 8 bits

ï£§ Parity bit generation and check

ï£§ Receive mode error signal detection (parity error)

ï£§ Transmit mode error signal detection and automatic re-transmission of data

ï£§ Supports both direct convention and inverse convention

â¢ Bit rate can be selected using on-chip baud rate generator.

â¢ Three types of interrupts: Transmit-data-empty, receive-data-full, and communication-error

interrupts are requested independently.
