Each read/write DMA byte count register contains the number of bytes
transferred on that channel in the current DMA transfer.
Writing to the channel x source address or destination address register
clears the channel x byte count register. The channel x byte count
register also is cleared when its count reaches the value in the channel
x block length register. Reset clears the byte count registers.
