Section 17 Smart Card Interface
17.1 Overview
The serial communication interface (SCI) supports a subset of the ISO/IEC 7816-3 (identification
cards) standard as an extended function.
Switching between the normal serial communication interface and the smart card interface is
carried out by means of a register setting.
17.1.1 Features
Features of the smart card interface are listed below.
• 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
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.
