Note:
There are registers which guarantee a value to remain the same before and after a function call,
and registers which do not. Rules for guaranteeing register values for different CPU types
appear in table 9.5.

Important Information When
Programming
If there is a valid value in a
register when a function is
called, the calling function saves
the value; the called function
can use the register without
saving its contents
The contents of the registers
used within the function are
saved, and are restored on
return
