Section 11 Serial Communication Interface
b. 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:
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.
• 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.
