The No Operation (NOP) instruction performs no function. Programs use NOPs as a time-killer for synchronization purposes. Programs also use NOPs to break up long sequences of non-interruptible instructions in order to allow the STIC to interrupt the CPU or request the bus. The opcode format is as follows.

   0000:0000:0011:010x
