If the fast termination option is used with external burst request mode (Figure 6-14), an
extra DMA cycle may result on every burst transfer. Normally, DREQ is negated when
DACK is returned. In the burst mode with fast termination selected, a new cycle starts
even if DREQ is negated simultaneously with DACK assertion.

1. To cause another DMA transfer, DREQx is asserted after DACKx is asserted and before
2. DACKx and DONEx (DMA control signals) are asserted in the source (read) DMA cycle.
