stack Pointer (SP)

It is also a 16 bit  register and a  memory  pointer similar to  program counter. It holds  the memory  address of the  top of the stack. Stack is a  part of  the memory used to  store  data temporarily  especially  while execution of subroutine.  Data  stored  last is  read  first  in the  stack i e last in first  out ( LIFO).  The use of stack  pointer will be explained in more detail in chapter5.
