3.4.9 Stack addressing
80
[Function]
[Description example]
[Illustration]
The stack area is indirectly addressed with the stack pointer (SP) contents.
This addressing method is automatically employed when the PUSH, POP, subroutine call and return
instructions are executed or the register is saved/reset upon generation of an interrupt request.
With stack addressing, only the internal high-speed RAM area can be accessed.
