NOP
Instruction Name | No Operation |
Mnemonic | NOP |
CP1610 Clock Cycles | 6 |
Interruptible | Yes |
Opcode Range | $0034-$0035 |
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
where: x is ignored
