Section 15 Serial Communication Interface (SCI and IrDA)
15.7
IrDA operation can be used with SCI_2. Figure 15.21 shows an IrDA block diagram.
If the IrDA function is enabled using the IrE bit in KBCOMP, the TxD2 and RxD2 pins in SCI_2
are allowed to encode and decode the waveform based on the IrDA standard 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 standard version 1.0.
In the system defined by the IrDA standard version 1.0, communication is started at a transfer rate
of 9600 bps, which can be modified as required. 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.
