Question: A simple byte oriented microcontroller has a 1 6 - bit stack pointer ( SP ) register that points to the next empty memory location

A simple byte oriented microcontroller has a

16 -

bit stack pointer

(

)

register that points to the next empty memory location in the stack. A PUSH instruction loads an operand into the stack and then decrements the SP; a PULL instruction increments the SP and then unloads an operand from the stack. Which of the following is NOT a common use for a memory stack of the type described above?

.

The stack can be used to store parameters passed among subprograms.

.

The stack can be used to store program counter return links for nested subprograms.

.

The stack can be used to sequentially store synchronously received input data.

.

The stack can be used to store and retrieve randomly accessed database records.
