Advanced Embedded Systems Question:
Explain issues related to stack and bank 1?
Answer:
☛ Bank 1 uses the same RAM space as the stack.
☛ Stack pointer is incremented or decremented according to the push or pop instruction.
☛ If the stack pointer is decremented it uses locations 7,6,5… which belongs to register bank 0.
☛ If a given program uses R1 then stack is provided new memory location.
☛ The push instruction may also take stack to location 0 i.e.it will run out of space.
