PA11/PA9 and PA12/PA10 Pin configuration for STM32C071RBT6

[curiocity]

Hi,
Could someone please explain the meaning of this image? It's a snapshot from CubeMX GPIO section.
Does it imply that PA12 and PA10 can be used as a single pin, or does it mean something else?

The reason I am asking is I am not able to Turn ON OR Toggle the pin PA12 I don't understand the reason why this pin gives me problem

By default, those pins are PA11 and PA12. You can set them as PA9 and PA10 instead with these checkboxes:

Hi TDK,

Thanks for your reply 

I have not clicked on the checkbox still my PA12 pin is not used as output I have tried toggling to this pin, to verify my toggling is Ok I selected another pin which works ok but when I am going to use PA12 The pin is not toggling You can see in my attached image 

Also, if I try to click on the check boxes then I cannot be able to click it looks like these checkboxes are disabled

Show your board, schematic, connections, etc. You're missing something in there.

Include your IOC.
