STM32H753ZIT6- ALE &CLE

Hello team,

I am trying to connect external NAND flash with STM32H753ZIT6.

my concern is with respect to FMC_ALE and FMC_CLE pins as, in Pin no. 80 and 81 these are multiplexed with address lines whereas pin no 98 and 99 can also be used as FMC_ALE and FMC_CLE.

i just need to confirm both the pins are same or is there any difference in these pins?

 

Thanks

Nikhil

    Hello,

    CLE and ALE NAND memory signals are multiplexed respectively with addresses A16 and A17.
