mc9s12xd64 irq set to lowest priority

Workaround is:

Where using IRQ in edge-sensitive mode then configure the interrupt 
priority levels of all interrupts being used to ensure that the IRQ
request always has the lowest priority.

My Question: How do I lower IRQ interrupt priority? Seems there is only access to 8 vectors to change their priority. All int's are priority 1 out of reset by default. I use several interrupts and would have to raise their priority while leaving IRQ priority at 1 so IRQ is the lowest.

Anyone know how to accomplish this?
