L412 documentation error.

[re.wolff9]

I think I found a documentation error in the L412 datasheet.

The Quadspi is documented to support two banks in the QUADSPI module description, but I can only find the pins for BK1, which I assume is the first bank.

My guess is that the QUADSPI module supports two banks, but that on the "no-big-packages" 'L412 chip the second bank is not available.

I've put "Whoa! fun feature, lets see if I can use that", so I'm not yet very familiar with the feature.... so I might be wrong.

But If I'm right I think the 'L412 datasheet should not promote the second bank ...

Update: I've checked another datasheet and BK2 is indeed the name for the second bank, and as far as I can see, some required pins on BK2 are on "100+" packages.

Oh... Quick question for those who /are/ familiar with the QUADSPI: Does this work with SD cards?

Hello @re.wolff9​ ,

You are right, STM32L412 devices do not support the Dual bank.

I have raised this internally to correct the L412 datasheet and remove the following sentence:

Thanks for pointing out this issue.
