point, the last data of CSI is being transmitted. To start DMA transfer again, therefore, wait until transfer of CSI is
completed.

The fist trigger for consecutive transmission is not started by the interrupt of CSI. Start it by a software trigger.
CSI transmission of the second time and onward is automatically executed.
The DMA interrupt (INTDMA0) is generated as soon as the last data has been written to the transmit buffer. At this
Note The DST0 flag is automatically cleared to 0 when a DMA transfer is completed.
Writing the DEN0 flag is enabled only when DST0 = 0. To terminate a DMA transfer without waiting for
occurrence of the interrupt of DMA0 (INTDMA0), set DST0 to 0 and then DEN0 to 0 (for details, refer to
16.5.5 Forced termination by software).
