3.4.7 Stack addressing
[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/restored upon interrupt request generation.
Stack addressing can be used to access the internal high-speed RAM area only.
