@title NOP
@id 118
@desc {
No Operation does nothing. This instruction can be used for instruction alignment purposes. See Pre-UAL pseudo-instruction NOP on page AppxH-2472 for details of NOP before the introduction of UAL and the ARMv6K and ARMv6T2 architecture variants. Note The timing effects of including a NOP instruction in a program are not guaranteed. It can increase execution time, leave it unchanged, or even reduce it. Therefore, NOP instructions are not suitable for timing loops.
