STM32F401/RM0368 bad GPIOA->MODER reset value

[waclawek.jan]

As reported here, this is obviously incorrect.

Also, this has been already reported by Uwe Bonnes for 'F411/RM0383, which has indeed been corrected in the registers description, but the GPIO register map still contains the incorrect value. So, could ST please go through all low-end 'F4 RM and check/correct at both places where applicable?

Thanks,

Hi @Community member​ ,

Thank you for bringing this issue to our attention.

I confirm this issue in RM0368, RM0383, RM0401, RM0402 and RM0430.

The correct reset value of GPIOA_MODER register is 0xA800 0000.

I reported this issue internally.
