When nXDREQ is active and GDMA gets the bus in Demand mode, GDMA controller holds the
system bus until the nXDREQ signal becomes non-active. Therefore, the period of the active
nXDREQ signal should be carefully tuned such that the entire operation does not exceed an
acceptable interval (for example, in a DRAM refresh operation).
