This LSI includes serial communication interface 3 (SCI3). SCI3 can handle both asynchronous
and clocked synchronous serial communication. In asynchronous mode, serial data
communication can be carried out using standard asynchronous communication chips such as a
Universal Asynchronous Receiver/Transmitter (UART) or an Asynchronous Communication
Interface Adapter (ACIA). A function is also provided for serial communication between
processors (multiprocessor communication function).
Figure 14.1 is a block diagram of SCI3.
14.1
Asynchronous mode
SCI0010A_000120030300
Choice of asynchronous or clocked synchronous serial communication mode
Full-duplex communication capability
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.
On-chip baud rate generator allows any bit rate to be selected
External clock or on-chip baud rate generator can be selected as a transfer clock source.
Six interrupt sources
Transmit-end, transmit-data-empty, receive-data-full, overrun error, framing error, and parity
error.
Internal noise filter circuit (available for asynchronous serial communication only)
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 the case of a
framing error
