Bit 3 – DCCDMALEVEL1 DMA TriggerLevel 1

ValueNameDescription
0x0READDCC1 trigger is the image of STATUSB.DCC1D, this signals to the DMA that a data is available for read, this is the correct configuration for a channel that reads DCC1.
0x1WRITEDCC1 trigger is the image of STATUSB.DCC1D inverted, this signals to the DMA that DCC1 is ready for write, this is the correct configuration for a channel that writes DCC1.

Bit 2 – DCCDMALEVEL0 DMA TriggerLevel 0

ValueNameDescription
0x0READDCC0 trigger is the image of STATUSB.DCC0D, this signals to the DMA that a data is available for read, this is the correct configuration for a channel that reads DCC0.
0x1WRITEDCC0 trigger is the image of STATUSB.DCC0D inverted, this signals to the DMA that DCC0 is ready for write, this is the correct configuration for a channel that writes DCC0.
