For Multiword DMA transfers, the Device may negate IDE_DREQ[0:1] within the tL specified time once IDE_DACK[0:1
is asserted, and reassert it again at a later time to resume the DMA operation. Alternatively, if the device is able to co
tinue the transfer of data, the device may leave IDE_DREQ[0:1] asserted and wait for the host to reasse
IDE_DACK[0:1]#.
This signal can be negated by the host to Suspend the DMA transfer in process.
