ALE signal function

I'm trying to learn the use of signal ALE (dedicated pin). Does the ALE pin pulse when accessing to internal memory (FLASH,RAM)?. This's very important for emi reduction. And what about the ALE signal of CPLD?.

Thanks in advance for any comments.

Regards,

Yes, the ALE pin will pulse when accessing to the uPSD's Flash and SRAM as well as to the CPLD.
