Note The DST1 flag is automatically cleared to 0 when a DMA transfer is completed.
Writing the DEN1 flag is enabled only when DST1 = 0. To terminate a DMA transfer without waiting for
occurrence of the interrupt of DMA1 (INTDMA1), set DST1 to 0 and then DEN1 to 0 (for details, refer to
15.5.7 Forcible termination by software).
