13.11.5 Debug Communication Channels DMA connection

The DCC0 and DCC1 registers can be used as a source or a destination of a DMA channel. The DSU generates one DMA request per Debug Communication Channels. The level of this DMA request is selectable writing the CFG.DCCDMALEVELx bit. Writing a 0 to this bit will configure the DMA request to trig on DCCx register empty. Writing a 1 to this bit will configure the DMA request to trig on DCCx register full.
