17.5.3. When Write Command is issued to the device (Transfer Start Position)
ATA_CLK

ATD_OUT
The above figure is timing diagram that shows the transfer start position during write transfer by Ultra DMA Mode 5. The
steps for setting up the software used when transferring data are exactly the same as for when issuing a read command. The
meaning of each signal on the ATA Bus changes: IORDY becomes the transfer Ready signal that the device provides to this
controller; DIORN becomes the Strobe signal when transferring data to the device.
Following is the flow of each control signal at the transfer start position.
The following table shows the parameters when transfer starts.

Mode
A- Wait until DMARQ becomes active (“High”).
B- When transfer preparations inside the Controller are complete, set HA to “0h”, and CS0N and CS1N to “1”.
C- Wait for the specified time, then make the DMACKN active (“0”).
D- Wait until IORDY becomes active (“Low”).
E- Wait for the specified time, then transfer data to the device while changing the state of DIORN.
