I found it, thankyou for your reply. FSMC_NL for ALE purpose. While i was changed the configurations as per reference manual that was able to enable. Also working fine.

Why do you want to enable it if you don't know what is it's purpose?

It is used only for memories with multiplexed address/data buses, or in (quite rare) memories which require a latch signal for address.

What memory do you intend to connect to FSMC?
