This LSI has five independent serial communication interface (SCI) channels. The SCI can handle
both asynchronous and clocked synchronous serial communication. Asynchronous serial data
communication can be carried out with standard asynchronous communication chips such as a
Universal Asynchronous Receiver/Transmitter (UART) or Asynchronous Communication
Interface Adapter (ACIA). A function is also provided for serial communication between
processors (multiprocessor communication function).
16.1
• Choice of asynchronous or clocked synchronous serial communication mode
• Full-duplex communication capability
• On-chip baud rate generator allows any bit rate to be selected
• Choice of LSB-first or MSB-first transfer (except in the case of asynchronous mode 7-bit data)
• Four interrupt sources
• Module stop mode availability
Asynchronous Mode:
• Data length: 7 or 8 bits
• Stop bit length: 1 or 2 bits
• Parity: Even, odd, or none
• Receive error detection: Parity, overrun, and framing errors
• Break detection: Break can be detected by reading the RxD pin level directly in case of a
Clocked Synchronous Mode:
• Data length: 8 bits
• Receive error detection: Overrun errors
SCI0022A_000020020300
The transmitter and receiver are mutually independent, enabling transmission and reception to
be executed simultaneously. Double-buffering is used in both the transmitter and the receiver,
enabling continuous transmission and continuous reception of serial data.
The external clock can be selected as a transfer clock source.
Four interrupt sources ⎯ transmit-end, transmit-data-empty, receive-data-full, and receive
error ⎯ that can issue requests.
