Section 28 Serial Communication Interface with FIFO/IrDA Interface (SCIF/IrDA)
28.5 Infrared Data Communication Interface
The IrDA infrared data communication interface converts (modulates) the serial communication
data received from the SCIF2 channel into the data format used by the infrared data
communication, and transmits the data from the SCIF2_TXD pin to the infrared sensor/emitter.
Also, this module converts (demodulates) the infrared communication data transmitted from the
infrared sensor/emitter to the SCIF2_RXD pin into the data format used by the serial data
communication, and transmits the data to the SCIF2 channel.
