25.7.4.4 Linked List Abort
The DMA provides the ability to abort linked-list operation and block transfer operation on the rising edge of a event system trigger. Setting CHEVCTRLk.EVAUXIE=1 and CHEVCTRLk.EVAUXACT=3 enables linked-list abort triggering. On the rising edge of the event system trigger, the CHCTRLAk.LLEN bit is cleared to prevent further linked-list operation. The associated block transfer abort is covered in detail in Abort Trigger Source.
