Section 14 Smart Card Interface
14.1 Overview
As an extension of its serial communication interface functions, SCI0 supports a smart card (IC
card) interface conforming to the ISO/IEC7816-3 (Identification Card) standard. Switchover
between normal serial communication and the smart card interface is controlled by a register
setting.
14.1.1 Features
Features of the smart-card interface supported by the H8/3048 Series are listed below.
⢠Asynchronous communication
â Data length: 8 bits
â Parity bits generated and checked
â Error signal output in receive mode (parity error)
â Error signal detect and automatic data retransmit in transmit mode
â Supports both direct convention and inverse convention
⢠Built-in baud rate generator with selectable bit rates
⢠Three types of interrupts
Transmit-data-empty, receive-data-full, and receive-error interrupts are requested
independently. The transmit-data-empty and receive-data-full interrupts can activate the DMA
controller (DMAC) to transfer data.
