Use SEC to Reconfigure Interrupt Priorities on SC584

Hi,

while working on my latest project, I stumbled upon a problem regarding the Interrupt priorities on an SC584 DSP:
I think in order to fix it, I would need to change the priorities, so that the UART interrupts have a higher priority than the SPORT data interrupt. 

I figured, I Need to use the SEC in order to achieve this.
However, since the system I'm working on is already quite involved, I am not sure where to start; but maybe some of you can help me:

- What is nescessary in order to use the SEC? Do I have to define my own priority levels and masks?
- What is the minimal number of things to change? In the System, there are also other interrupts (e.g. CAN), do I need to give them each a own priority by Hand?

If some of you could help me with this problem, it would be great!

Thanks in advance,

Marius
