How do I find the address of a stack pointer?
The stack pointer is stored in 'SP' register.
You can see its value from the 'Registers' tab under the General Registers.
To find the start and end address of the stack open the . map file in the Debug folder of your project and search for .
What is the stack size of 6502?
Unlike its main rival the Z80, the 6502 had a size limit of 256 bytes for the hardware stack._{2 jan. 2023}
The stack pointer.
Addresses the last value written to the stack (pushed).
The stack base.
Is the address of the top of the stack, from which the stack grows downwards.

Where is the CPU stack stored?

Stack Memory
This section is usually located at the top of the memory space and grows downward as more data is added.
Stack memory employs an automatic allocation and deallocation of memory that stores temporary data created by functions or procedures.

In a 6502 microprocessor, stack is hardcoded between the memory addresses $0100 and $01FF. And it's in the zeroeth page of the memory. Memory page is a virtual concept that divides the RAM into bite-sized segments.
