This LSI includes a serial communication interface 3 (SCI3), which has independent two channels.
The 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).
Table 16.1 shows the SCI3 channel configuration and figure 16.1 shows a block diagram of the
SCI3. Since pin functions are identical for each of the two channels (SCI3 and SCI3_2), separate
explanations are not given in this section.
16.1
Asynchronous mode
SCI0011A_000020020200
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.
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
