Create a similar example using different, non-trivial e.
DUAL 4-INPUT POSITIVE-NAND 50-OHM LINE DRIVERS
The first instruction is done as an example. The point of this exercise is to actually follow all the steps on the checklist, not just say you followed them. And, as always, you must do the pre-labs datqsheet. You MUST follow these procedures or we will not accept your submissions. It is OK to use CodeWarrior to check your work and make corrections after you have done it by hand.

Why is it valid or invalid? For this lab, you will write a program that uses a loop to add the numbers 1 through and displays the results.
Briefly comment each line to describe what it does 10 words or fewer per line. The term counter limit refers to the maximum value the counter runs to e.
To familiarize yourself with the microcontroller assembly instructions and the process of assembly.
Put a brief comment at the beginning which describes the overall function of the code. Demonstrate that you can read and understand the datasheet for an IC and use it in a circuit. You do not have to use the assembly program or the simulator.
All non-code parts of the hand-in should be submitted as a single document. Using a checklist is your best defense against this in general, and in particular is extremely helpful for avoiding unnecessary point losses when handing in assignments for this course.
Paste a copy of the pre-lab portion of the Lab Writeup Checklist into your hand-in materials. For this lab, you will adapt the string hash program from lab 1.
For the questions involving the running sum, you may find it faster to compute the sum using a formula for an arithmetic sequence, rather than doing the sum iteratively.
Also, see the course materials repository page. Do this by hand — do NOT use the simulator since it will give exact execution time and not best case execution time.
When you record your answers, use the conventions described in the discussion section.

For example, if Q7 is high, and Q6: Limit your answer to 40 words. Assume the voltage drop across the LED is 1. Pin 2 provides D0 to bus, Pin 5 provides D1, etc. Look carefully at the data sheet! Your program shall meet the following requirements: Machine code is fetched from memory and the instructions described are executed by the processor. Pick an instruction where the exact execution time differs from the best case execution time and explain why in one sentence.
This includes performing operations shift, add, subtract, clear on registers and memory locations and copying values from one location to another. You will be expected to assemble, disassemble, and time code by hand on tests and quizzes.
Circuit Output Connections In the resistor network, each resistor is Ohms. For the questions in part B. We suggest each of the two students in your lab group be “in charge” of one of the two parts of the lab parts to help divide the work.
