What is a stack pointer register? - 8085
What is a stack pointer register, describe briefly.
-The Stack pointer is a sixteen bit register used to point at the stack.
- In read write memory the locations at which temporary data and return addresses are stored is known as the stack.
- In simple words stack acts like an auto decrement facility in the system.
- The initialization of the stack top is done with the help of an instruction LXI SP.
- In order to avoid program crashes a program should always be written at one end and initialized at the other.
