NAME

       interrupt.h

SYNOPSIS

   Macros
       Global manipulation of the interrupt flag
       The global interrupt flag is maintained in the I bit of the status register (SREG).

       Handling interrupts frequently requires attention regarding atomic access to objects that
       could be altered by code running within an interrupt context, see <util/atomic.h>.

       Frequently, interrupts are being disabled for periods of time in order to perform certain
       operations without being disturbed; see Problems with reordering code for things to be
       taken into account with respect to compiler optimizations.
