Note: To terminate the data burst, the Device shall negate DMARQ within the TL of the assertion
of the current IORD# or IOWR# pulse. The last data word for the burst should be transferred
by the negation of the current IORD# or IOWR# pulse. If all data for the command has not been
transferred, the device shall reassert DMARQ again at any later time to resume the DMA operation.
