STM32G473/4 FMC/FSMC feature, pin called FMC_NL and FMC_NADV in datasheet DS12712 rev 5

[wb0gaz]

I'm working on migrating a design from STM32F405 series to STM32G473 series, both LQFP100 package, both use FSMC for access to external SRAM (in multiplexed mode; I have separate address latches clocked from FMC_NADV capturing A0..A15 from D0..D15.)

When verifying pin-by-pin alternate function definitions, I encountered FMC_NL (assigned through PB7) where I expected to find FMC_NADV (assigned through PB7.)

On further checking, I see that datasheet for G473 (DS12712 rev 5 is the version I downloaded and am referencing) cites FMC_NL only in the pin/alternate function definitions, and FMC_NADV in the timing diagrams.

The reference manual (RM0440) doesn't appear to site either pin name.

Is reference FMC_NL in the pin alternate function definitions to be taken as a typo which should read FMC_NADV?

Thank you

Hello @wb0gaz 

It is already mentioned in the reference manual figure 52. FMC_NL (or NADV) 

I agree, it should have been explicitly detailed in the datasheet.
