IrDA Operation

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.
