Goggle &amp;quot;volatile C keyword&amp;quot; see what you get.&lt;/p&gt;

&lt;p&gt;
The correct question is when should you use it. T answer would be
to access hardware registers, memory mapped hardware, and global
variables that are written to by an interrupt.&lt;/p&gt;

&amp;#39;&lt;b&gt;volatile&lt;/b&gt;&amp;#39; is a standard &amp;#39;C&amp;#39; keyword - its meaning in C51
is no different from any other &amp;#39;C&amp;#39; compiler.&lt;/p&gt;

&lt;p&gt;
You should look it up in any &amp;#39;C&amp;#39; textbook...&lt;/p&gt;
