There are at least two attributes to func declaration - "reentrant" and "critical" (defined in iomacros.h)
First one disables interrupts on funct entry and enables on exit. Another one saves r2, disables ints on exit and restores its state on exit. Read docs (which are in libc/doc) for more info. ~d P.S. dint/eint is not a proper (but possible) workaround On Friday 04 October 2002 17:10, Shehata, Karim wrote: > Hello everyone! > > In IAR's icc430 compiler, there's a keyword "monitor" that can be used when > declaring a function to disable all interrupts during it's execution.
