I am using Freescale S08JM60 MCU in my project. Is there any way to change interrupt priority in this MCU? The priority is already pre-defined in the datasheet. But it does not mention the priority can be changed. Currently USB's interrupt priority is in the middle of the interrupt vector table. I like to change its priority to the highest. How can I achieve this?

Even if it was possible to change interrupt priority, it most likely won't help you. What you would gain if lower priority interrupt happened fraction of us sooner than the most most top priority interrupt? - Nothing, unless you use some interrupt nesting schema. And interrupt nesting is possible without changing interrupt priorities.

Hi

Unfortunately this is not possible on the S08JM family.
