3.4.9 Stack addressing
[Function]
The stack area is indirectly addressed with the stack pointer (SP) contents. This addressing is automatically
employed when the PUSH, POP, subroutine call, and return instructions are executed or the register is
saved/restored upon generation of an interrupt request.
Stack addressing is applied only to the internal RAM area.
