'[SX]: Interrupts heat up chips??'

I doubt the problem is caused by the interrupts, but it is more likely that
it is an effect of something the interrupt routine is doing... or that the
code is not doing when the interrupt is running.

Hot chips are most often caused by
A) IO pins that are shorted or "fighting" against some external load. (see: )

B) Unused IO pins that are floating; not pulled up or tied to ground (see: )

The "effect of something the interrupt routine is doing" could be as simple
as changing the frequency or pattern of RF energy that the chip is
broadcasting into its own floating IO pins.
