DMARQ
If the Card cannot continuous, minimum cycle time DMA transfers, it may negate DMARQ within the time specified
from the state of a DMA transfer cycle suspend the DMA transfers in progress and reassert the signal at a lather time
to continue the DMA operation.
This signal may be negated by the host to suspend the DMA transfer in progress.
