12. Serial Communication Interface
⎯ Data length:
8 bits
⎯ Receive error detection: overrun errors
• 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.
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.
