STM32H503CBT6 Debug pins PA14/PA13 in IOC orange colored not green

I switched from an STM32F103C8T6 project template to an STM32H503CBT6.
When programming the pins PA13/PA14 to DEBUG_JTMS_SWDIO resp. DEBUG_JTCK_SWCLK these pins turn to color orange, indicatiing there is some conflict.

On the F103 configuration I recall that I had to tick Serial Wire Debug in the Debug section of "SYS".

This lacks in the H503 configurator. How do I manage it to get the pins conflict free?

Hello @chriskuku 

First let me thank you for posting.

Under [Debug] activate debug : serial wire and you will get the pins  PA13/PA14 to DEBUG_JTMS_SWDIO resp in green .

Yes, thanks, it's moved under TRACE and DEBUG.
