Irq priorities

[EXTERNAL B. M. (P. ST-FIR/Eng) <ext...@de...>]

Hi there,

I have a question about the priority for the irqs.=20
I found that the priorities for the other CPUs, set in the setup-sh*.c
are set as followed:
low priority (2) for timers
low priority (3) for sci(f)=20
high priority (7) for dma
This doesn't make sens to me. I would give timers a high priority, so
they keep acurate and dma a low priority.=20

Are there any rules for setting the priority for interrupts?=20

Regards

Markus
