32 bit limitation of MUL in ARM Assembly : <p>In ARM Assembly each register can contain 32 bits/1 word of information stored in it. That's why when you try to store a value larger than 255 it gives you an error</p>

<p>However, the MUL instruction seems to not have this limitation. You can multiply two registers, each of them having the value of 255 for instance, and store the result in a third register without any errors. How does this happen? Shouldn't the destination register be unable to store values beyond 255?</p>
