STM32G030C8t6 pin conflict!

[Ala]

hey there,

I have a STM32G030C8t6 which I wish to configure. in CubeMX when I focus on PA11 or PA12, I can see a bracket where this is mentioned:

PA11[PA9]

PA12[PA10]

what does it mean? does it mean they are somehow connected or related?

can anyone explain it?

thanks in advance

See DS12991 datasheet: Table 12 Foot note 4: "Pins PA9 and PA10 can be remapped in place of pins PA11 and PA12 (default mapping), using SYSCFG_CFGR1 register."

Check the other foot notes to avoid surprises.

so if I set SYSCFG_CFGR1 register in my code, I can use those Pins alternatively, right?

and the whole process should be done without CubeMx right?

Correct
