.PP
.RI "\fBGlobal manipulation of the interrupt flag\fP"
.br
The global interrupt flag is maintained in the I bit of the status register (SREG)\&.
.PP
Handling interrupts frequently requires attention regarding atomic access to objects that could be altered by code running within an interrupt context, see <\fButil/atomic\&.h\fP>\&.
.PP
Frequently, interrupts are being disabled for periods of time in order to perform certain operations without being disturbed; see \fBProblems with reordering code\fP for things to be taken into account with respect to compiler optimizations\&.
