11.5.1
In this example, receive data of the on-chip IrDA is transferred to external memory using DMAC
channel 3. Table 11.8 shows the transfer conditions and register settings. In addition, it is
recommended that the trigger for the number of receive FIFO data bytes in IrDA be set to 1
(RTRG1 = RTRG0 = 0 in SCFCR).
