note 4 : Inactive condition of Dreq is Dack="L"

And when next DMA transfer exists, spec when Dreq turns to active is valid the latest one of twh(Dreq) or td(CTRL-Dreq).

note 5 : Write is done in the overlap period when Dack and WR is active "L".

Spec from the positive edge is valid from the fastest inactive signal.

Spec of pulse width is valid of the overlap period of active "L".

note 6 : Read is done in the overlap period of Dack and RD is active "L"

Spec from the negative edge is valid from the latest signal.

Spec from the positive edge is valid form the fastest inactive signal.

Spec of pulse width is valid during active "L" overlap period.
