• Manufacturer: Renesas Electronics Corporation.

This LSI is equipped with a serial communication interface with FIFO/IrDA interface
(SCIF/IrDA) that supports the infrared data communication function. The SCIF/IrDA consists of a
serial communication interface with built-in FIFO buffers (SCIF) and infrared communication
data modulation/demodulation units. By specifying the IrDA input/output options, infrared data
communication can be performed with the infrared sensor/emitter in the same way as the
synchronous serial data communication.
The SCIF/IrDA uses channel 2 (SCIF2) as a serial communication channel. Note that some part of
the operating specification differs from that of channel 0 and 1 (SCIF0, SCIF1) in the serial
communication interface with FIFO (SCIF).
28.1
The SCIF/IrDA has the following features.
• Infrared data communication function
• Asynchronous serial communication mode
Infrared data communication compliant with the IrDA standard 1.0 can be performed.
This function modulates and demodulates the data format supported by serial communication
to the data format supported by infrared data communication.
Serial data communication is executed using an asynchronous system in which
synchronization is achieved character by character. 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).
There is a choice of 8 serial data transfer formats.
 Data length: 7 or 8 bits
 Stop bit length: 1 or 2 bits
 Parity: Even/odd/none
 Receive error detection: Parity, framing, and overrun errors
 Break detection: A break is detected when a framing error lasts for more than 1 frame
length at Space 0 (low level). When a framing error occurs, a break can also be detected by
reading the SCIF2_RXD pin level directly from the serial port register (SCSPTR).
