If the IrDA function is enabled using the IrE bit in IrCR, the TxD5 and RxD5 pins in SCI_5 are
allowed to encode and decode the waveform based on the IrDA Specifications version 1.0
(function as the IrTxD and IrRxD pins). Connecting these pins to the infrared data transceiver
achieves infrared data communication based on the system defined by the IrDA Specifications
version 1.0.
In the system defined by the IrDA Specifications version 1.0, communication is started at a
transfer rate of 9600 bps, which can be modified later as required. Since the IrDA interface
provided by this LSI does not incorporate the capability of automatic modification of the transfer
rate, the transfer rate must be modified through programming.
Figure 14.36 is the IrDA block diagram.
