ns
All of the RD or WR asserted pulse must fall inside of the DMACK asserted pulse. The DMA cycle uses DMACK as the chip select. DMACK
overrides SA<3:0>, forcing selection of the buffer memory port. DREQ goes low during the next-to-last transfer of the burst if DLCR4<2> = 1, and
can be extended to the last transfer cycle by setting DLCR4<2> = 0.

BURST INTERRUPTED
Burst can be interrupted by negating DMACK. Burst will resume when DMACK is reasserted.
