DAC Interaction with DMA

Default
Value
The DMA controller acknowledges the interrupt request from the DAC and will
transfer data from DMA memory to the DAC data registers. Since the DMA
controller shares the Data bus and can only transfer one word at a time, DMA
Channel 0 will be the first to transfer data from DMA memory to the DAC data
register followed by DMA Channel 1.
