Input and output data in clock asynchronous mode are converted into the format supporting IrDA physical layer
specification v.1.0. The UART0 transmit data is encoded and output in the RZI (Return to Zero Inverted)
format. Input data in the RZI format is decoded to the NRZ (None Return to Zero) format and becomes the
UART0 reception input data. Refer to the 17.1.2 Clock Asynchronous (UART) Mode for details on clock
asynchronous mode.
Table 17.21 lists specifications of IrDA mode. Figure 17.37 shows a block diagram. Figure 17.38 shows a
register associated with IrDA mode. Figure 17.39 shows an IrDA operation.
