volatile means that it is a memory location (register) which can change its =

value without being changed by code generated by the compiler. That is, the =

compiler can not rely on that the memory location has the same value that i=
t =

previously was set to by compiled code. This is true for all registers that=
 can =

be changed by hardware modules.
