For those of you that use the IAR tool suite, and haven't yet found out the hard way, there is a bug in the arithmetic routines that causes interrupts to be globally disabled when the result of certain operations is zero.

IAR have a patch; you should contact them for download details.

Colin

IAR has found a way to simulate the NMI facility of the x86. :)

You can put lipstick on a pig, but it is still a pig.

I've never met a pig I didn't like, as long as you have some salt and pepper.
