title: What is the difference between RCR and ROR?
body: <p>I understand the from the terms that <code>RCR</code> would rotate the bit from the right to left, taking the <strong>bit from the carry</strong> while <code>ROR</code> will rotate the bit from right to left, taking the <strong>bit from the right</strong> but is that the only difference between them? If this is so, both of the instructions seem to do the same work. Please help out. Thanks </p>
