Instruction Synchronization Barrier.
where:
cond
ISB acts as an instruction synchronization barrier. It flushes the pipeline of the processor, so that
all instructions following the ISB are fetched from memory again, after the ISB instruction has
been completed.
This instruction does not change the flags.
