As a result, the values in the DMAC are as shown in table 11.10 when the fourth transfer ends,
depending on whether the address reload function is on or off.

Notes: 1. An interrupt is generated regardless of whether the address reload function is on or off,
11.5.3
In this example, DMA transfer is performed between the external memory specified by indirect
address (transfer source) and the SCIF transmitter (transfer destination) using DMAC channel 3.
Table 11.11 shows the transfer conditions and register settings. In addition, the trigger for the
number of transmit FIFO data bytes is set to 1 (TTRG1 = TTRG0 = 1 in SCFCR).
