Hi @jinu_mohan ,
Thanks for your trust!
You mean, in the internal group:GPIO6_7_8_9_IRQn, whether you can set the individual priority, right?
No, to this one, it share the IRQ.
So, if you want to set the infividual priority, you need to use the different IRQ.
You can use this GPIO:

Then different pin has different IRQ, you totally can set it's own priority.
Wish it helps you!
Best Regards,
Kerry
