Note 4: *Dack="L" level is the condition for inactive *Dreq, and the latter signal of twh(Dreq) or ten(CTRL-Dreq)
becomes valid as the specification of active *Dreq at the time of next DMA transfer.
Note 5: Writing through the combination of *Dack, *HWR and *LWR is carried out during the overlap of active (“L”).
The specification of the rising edge is valid from the earliest inactive signal.
The specification of pulse width is valid during the overlap of active (“L”).
Note 6: Reading through the combination of *Dack and *RD is carried out during the overlap of active (“L”).
The specification from the falling edge is valid from the latest active signal.
The specification from the rising edge is valid from the earliest inactive signal.
The specification of pulse width is valid during the overlap of active (“L”).
Note 7: In 8-Bit Mode, D7~0 becomes valid.
