STM32WB09 Reference Manual & Datasheet Disagree on GPIO Alt Functions

[physgun]

In the STM32WB09's Reference Manual, RM0505 Rev 3, Table 8: PA10 and PA11 have SWD modes for their AF4.

However, in the STM32WB09 datasheet, DS14210 Rev 6, Table 6 and Table 7: PA10 and PA11 have no AF4.

Which one is correct?

Hello @physgun 

Thank you for having reported this issue.

I am checking it internally and I will return to you with details about the corrective actions we will take.

Hello @physgun ,

After internal checks, I confirm that the information on the STM32WB09 datasheet (DS14210 Rev 6) is correct, and the RM0505 must be updated (no AF4 SWD modes on PA10 and PA11).

We'll take the necessary action to fix this point on next planned Reference Manual release (Request tracked through an internal ticket number: 223111 - This ticket is only for reference and is not available outside of ST).

Thank you for your contribution.
