You never want two bits to be changing at the same time, because they are never at exactly the same time, so there is a glitch when one has changed but not the other. AS code with one bit changing at a time is called a Gray code. | |

One should never rely upon two asynchronous signals to switch and precisely the same time; if one expects them simultaneously, one must be prepared for either to actually happen first. | |
