Section 18 Smart Card Interface
Section 18 Smart Card Interface
18.1 Overview
As an additional serial communications interface function, a smart card (integrated circuit card)
interface (SCI) that is compatible with the T = 0 data transfer protocol of ISO/IEC standard 7816-
3 (identification card) is supported. Register settings are used to switch between the ordinary serial
communication interface and the smart card interface.
18.1.1 Features
The smart card interface has the following features:
• Asynchronous mode
⎯ Data length: Eight bits
⎯ Parity bit generation and check
⎯ Receive mode error signal detection (parity error)
⎯ Transmit mode error signal detection and automatic re-transmission of data
⎯ Supports both direct convention and inverse convention
• Bit rate can be selected using on-chip baud rate generator.
• Three types of interrupts: Transmit-data-empty, receive-data-full, and communication-error
interrupts are requested independently.
