Hi, thers STM32G473CE datasheet error. in DS12712 Rev 4 (and some other G4 datasheets) PA10's AF4 is showen as I2C2_SDA in the AF table, but in the port AF lisst its I2C2_SMBA. cube also just shows I2C2_SMBA. And it is SMBA not SDA.

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!

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.
