The fist trigger for consecutive transmission is not started by the interrupt of CSI. In this example, it start by a software
CSI transmission of the second time and onward is automatically executed.
A DMA interrupt (INTDMA0) occurs when the last transmit data has been written to the data register.
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 the DST0 bit to 0 and then the DEN0 bit to 0 (for details,
refer to 17.5.5 Forced termination by software).
