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

Features of the smart-card interface supported by the H8/3048 Group are listed below.

• Asynchronous communication

 Data length: 8 bits

 Parity bits generated and checked

 Error signal output in receive mode (parity error)

 Error signal detect and automatic data retransmit in transmit mode

 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.
