12. The instruction that can affect stack pointer is
Answers
Answer:
he stack is a LIFO (last in, first out) data structure implemented in the RAM area and is used to store addresses and data when the microprocessor branches to a subroutine. Then the return address used to get pushed on this stack. Also to swap values of two registers and register pairs we use the stack as well.
In the programmer‘s view of 8085, only the general purpose registers A, B, C, D, E, H, and L, and the Flags registers were discussed so far. But in the complete programmer’s view of 8085, there are two more special purpose registers, each of 16-bit width. They are the stack pointer, SP, and the program counter, PC. The Stack Pointer register will hold the address of the top location of the stack. And the program counter is a register always it will hold the address of the memory location from where the next instruction for execution will have to be fetched.
