Hi there

Looking at several processors at the moment but ARM7 and Coldfire in
particular. I like the popularity of ARM and associated tools, but cant get
over the fact that the interrupt structure within them (only two priority
levels) is pants. Coldfire has 7 or 8 nestable levels.

I would appreciate anyones view on this.

Look on the freescale site for some app notes on the MAC7xxx series
MCUs. There is an app note explaining how to do nested interrupts
with the ARM. Their ARM controllers, as has most of their other
families, a very capable interrupt controller.
