Section 14 Serial Communication Interface 3 (SCI3, IrDA)
The serial communication interface 3 (SCI3) can handle both asynchronous and clock
synchronous serial communication. In the asynchronous method, 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).
The SCI3 can transmit and receive IrDA communication waveforms based on the Infrared Data
Association (IrDA) standard version 1.0.
14.1 Features
• Choice of asynchronous or clock 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
• On-chip baud rate generator, internal clock, or external clock 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.
• Use of module standby mode enables this module to be placed in standby mode independently
when not used. (The SCI3 is halted as the initial value. For details, refer to section 5.4, Module
Standby Function.)
Asynchronous mode
• Data length: 7, 8, or 5 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 RXD3 pin level directly in the case of a
framing error
