Hi @felix ,

I confirmed the issue, there is mistake in these datasheets: DS12712 and DS12997.

The pin description list is the correct one:

For Pin PA10, the alternate function is I2C2_SMBA.

For Pin PA8, the alternate function is I2C2_SDA. I reported this issue internally.

Internal ticket number: 131036 (This is an internal tracking number and is not accessible or usable by customers).

I think you are right ... congratulations for this ... I never saw an error in these lists before - usually I think (hope :) ) they are checked very very carefully..

In the Pin description list PA8 shows "I2C2_SDA" and PA 10 shows "I2C2_SMBA" (same datasheet, chapter 4.10), but in the Alternate function list (chapter 4.11) for I2C2 these two functions at PA8/PA10 are just mixed up!
