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 the DST1 bit to 0 and then the DEN1 bit to 0 (for details,
refer to 17.5.5 Forced termination by software).
