Purpose of FSMC_NL pin and How to enable

[AFaya.1]

HI,

I am working on STM32F413zh and i am trying to enable FSMC_NL gpio pin. I dont't know what is the purpose and how to enable this pin in STM32cubeMX. Please give me the support.

Thankyou.

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?

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.
