## 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.
