hi for setting interrupt priority setting  in IMXRT1060s we are using 

NVIC_SetPriority(GPIO6_7_8_9_IRQn, 4);

is there any method to set the individual priority of these combined interrupts

because currently we are using four interrupts in this combined irqn we need to set higher priority to one specific pin interrupt

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
