PRELAB
To complete this prelab, you may find it useful to look at the AVR Starter Guide
and the AVR Instruction Set Manual. If you consult any online sources to help
answer the prelab questions, you must list them as references in your prelab.
1. What is the stack pointer? How is the stack pointer used, and how do you
initialize it? Provide pseudocode (not actual assembly code) that illustrates
how to initialize the stack pointer.
2. What does the AVR instruction LPM do, and how do you use it? Provide
pseudocode (not actual assembly code) that shows how to setup and use
the LPM instruction.
3. Take a look at the definition file m128def . inc (This file can be found in the
Solution Explorer - Dependencies folder in Atmel Studio, assuming
you have an Assembler project open and you have already built an assembly
program that includes this definition file. Two good examples of such a
project would be your Lab 1 and Lab 3 projects.) What is contained within
this definition file? What are some of the benefits of using a definition file
like this? Please be specific, and give a couple examples if possible.
