    I am using STR710FZ2T6, from the datasheet we can see the Address Hold Time is just 3ns, actually I measured with oscilloscope, the time less than 3ns, but my LCD(SED1335) and some other chips need the Address Hold Time to be at least 10ns. :-[

    Is there anyone can tell me how to do with this problem?

    No one can help me? Or no one encounter this issue?

    In my project RTL8019AS and LCD(SED1335), need the Adress Hold Time to be 10ns at least. I am afraid if I can not meet this, system can not run stable.

    More problem found, even the FLASH(M29W160) can not run stable due to the address hold time, but the FLASH do not need more Address Hold Time(0ns).

    I wonder if i can set some register to make this time a little longer, maybe 10ns is enough, but unfortunately no such register provided.

    please help me, this problem make me creazy.
