It is nothing but telling to compiler that this variable
will change its value at anytime by means of anything and
compiler should not make any assumption about this variable.
Normally compiler will assume that some variable will be
constant during runtime. This may lead error in checking a
registor value repeatedly. Because the register value may
be changed by anything. So for these kind of variables
should be declared 'volatile' and it be checked each time
appears in the code with out any assumption.
