I am trying to interface At89C52 with Simpletech Solid-state IDE flash disk with combination of 16-line data bus , 2-line chip select, 3-line address , RD & WR signals.

I have followed ata/atapi spec and many other design and sample codes . but when i captured the signal by connecting Flash disk with singal board computer then i found there is some difference in steps.

If any one did this task please help me.
