Change IRQ Handler during runtime

Hi,

I have a highly optimized IRQ handler for my PWM Interrupts (PWM1_IRQHandler).

For different application modes I want to use another IRQ handler because a switch or ifelse statement is wasting too much time. So now my question: is it possible to overwrite the IRQ functionPtr or whatever to call different IRQ routines? Are they determined by compile-time? Is this memory region accessible during runtime?

Regards,
Hans

What about remapping your vector table to RAM and then change PWM interrupt adress ?
