REJ09B0260-0200
There is a single serial data communication format.
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:
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.
Asynchronous communication
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.
Data length:
Receive error detection: overrun errors
LSB-first or MSB-first transfer
Inversion of data logic level
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
8 bits
