Synchronous mode
Serial data communication is synchronized with a clock signal. The SCI can communicate
with other chips having a synchronous communication function. There is one serial data
communication format.
— Data length:
— 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.
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.
