In this example, DMA transfer is performed between the external memory specified with the
indirect address (transfer source) and the SCIF transmitter (transfer destination) using DMAC
channel 3. Table 14.10 shows the transfer conditions and register settings. In addition, it is
recommendable that the trigger for the number of transmit FIFO data is set to 1 (TTRG1 = TTRG0
= 1 in SCFCR).
