title: Equivalent for NOP in C for Embedded?
body: <p>I use KEIL to compile a program.</p>
  
  <p>The program uses the code</p>
  
  <blockquote>
    <p>asm("NOP");</p>
  </blockquote>
  
  <p>Unfortunately KEIL compiler does not accept the statement.</p>
  
  <p>The idea is to introduce a delay by using NOP (no operation) assembly code.</p>
  
  <p>What is the actual equivalent of this in C ? Does this vary with the embedded controller that I use?</p>
