• Full-duplex communication

The transmitting and receiving sections are independent, so the SCI can transmit and receive

simultaneously. The transmitting and receiving sections are both double-buffered, so serial

data can be transmitted and received continuously.

• The following settings can be made for the serial data to be transferred:

 LSB-first or MSB-first transfer

 Inversion of data logic level

• Built-in baud rate generator with selectable bit rates

• Selectable transmit/receive clock sources: internal clock from baud rate generator, or external

clock from the SCK pin

• Four types of interrupts

Transmit-data-empty, transmit-end, receive-data-full, and receive-error interrupts are requested

independently. The transmit-data-empty and receive-data-full interrupts from SCI0 can

activate the DMA controller (DMAC) to transfer data.

Features of the smart card interface 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 transmit/receive-error interrupts are requested

independently. The transmit-data-empty and receive-data-full interrupts can activate the DMA

controller (DMAC) to transfer data.
