This LSI has four 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). The SCI also supports the smart card (IC
card) interface supporting ISO/IEC 7816-3 (Identification Card) as an extended asynchronous
communication mode. Figure 14.1 shows a block diagram of the SCI.
14.1
• 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 state specifiable
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
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 (except for the smart card
interface).
The interrupt sources are transmit-end, transmit-data-empty, receive-data-full, and receive
error. The transmit-data-empty and receive-data-full interrupt sources can activate the DMAC
or DTC.
