I don't understand the question completely. Do you want to use nested interrupts?

Why do you want to do that?

Why can't you place the code (that is supposed to be in GPIO ISR) in PWM ISR?

Based on the timing requirement, you can also raise a flag within PWM ISR, and in the main code, place the do the work you want to do in the GPIO ISR.

Bravo Sai - well argued AND well explained/justified. And - you've outlined a (far) more standard & productive alternative!

ALWAYS agreeing w/poster requests - especially when they appear "unsound" - proves NOT best/brightest...
