When the IrDA function is enabled with bit IrE in IrCR, the SCI_0 TxD0 and RxD0 signals are
subjected to waveform encoding/decoding conforming to IrDA specification version 1.0 (IrTxD
and IrRxD pins). By connecting these pins to an infrared transceiver/receiver, it is possible to
implement infrared transmission/reception conforming to the IrDA specification version 1.0
system.
In the IrDA specification version 1.0 system, communication is started at a transfer rate of 9600
bps, and subsequently the transfer rate can be varied as necessary. As the IrDA interface in this
LSI does not include a function for varying the transfer rate automatically, the transfer rate setting
must be changed by software.
Figure 15.33 shows a block diagram of the IrDA function.
