13.1

Overview

The 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 chip is 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
• Built-in 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 and receive-data-full interrupts can activate the data transfer
controller (DTC) to execute data transfer
