DMA Count (0-1) Registers
This register contains the byte count for a DMA transfer. A zero value indicates that zero
bytes are transferred. As the DMA transfer progresses, the DCNT register is decremented.
When a DMA transfer completes with out errors, the final DCNT value is zero.
Software programs this register when performing Direct-Mode transactions. When
performing Linked-List-Mode transactions, this register is automatically loaded from the
count field of the current descriptor.
