Nop/Brk/Sleep - Processor and execution control

These instructions are various functions about processor execution. These instructions does nothing.
The nop instruction does nothing. It takes 1 byte and consume 2 execution cycles. It can be used for padding in some situations between two pieces of code. It can be used also for synchronisation for waiting some precise amount of time.
The brk instruction does nothing then stop execution juste after the brk. If the processor is in continuous running mode, it is switched into step mode.
The sleep instruction does nothing and terminate the actual time quantum of the virtual machine. The execution will be resumed in the next time quantum. One time quantum is allowed for each robot in each cycle of the MVI engine.
