|
|
shifted right by 2. This is used in situations such as loading a register
|
|
with the address of a function (or any other code fragment). For example, if
|
|
you want to load a register with the location of the function <code>main</code> then
|
|
jump to that function, you could do it as follows:
|
|
<pre class="smallexample"> ldi r2, main@word
|
|
jmp r2
|
|
</pre>
|
|
</body></html>
