The first instruction is done as an example. Do this by hand using the reference materials. Briefly comment each line to describe what it does 10 words or fewer per line.

DUAL 4-INPUT POSITIVE-NAND 50-OHM LINE DRIVERS

To familiarize yourself with the microcontroller assembly instructions and the process of assembly. Using a dataeheet is your best defense against this 774ls374 general, and in particular is extremely helpful for avoiding unnecessary point losses when handing in assignments for this course.

Create a similar example using different, non-trivial e. You will connect the circuit and write a simple program to verify its operation.

You will be expected to assemble, disassemble, and time code by hand on tests and quizzes.

For branch instructions, insert labels at the appropriate locations and use the label values in your disassembled assembly code. Look carefully at the data sheet! For example, if Q7 is high, and Q6: Confirm the operation using the simulator to make sure you got it right, which you need document only by saying “checked with simulator” in your hand-in.

It is OK to use CodeWarrior to check your work and make corrections after you have done it by hand.

This lab uses a flip-flop to hold a data value on a bar graph LED. Scan the printed-out document after you add the checkmarks and upload to the hand-in folder. 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. You MUST follow these procedures or we will not accept your submissions. Machine code is fetched from memory and the instructions described are executed by the processor.

This lab uses the same circuit as Lab 2 part A. BUT, we expect both of you to understand and participate in the execution of both labs.

You do not have to use the assembly program or the simulator. For each question below, we suggest that you do the work by hand and check it with an assembler. Do this 74lls374 hand — do 74l3s74 use the simulator since it will give exact execution time and not best case execution time. Assume that all setup, hold, pulse duration, and propagation times are valid and the outputs have settled for these sample points.

Why is it valid or invalid? Demonstrate that you can read and understand the datasheet for an IC and use it in a circuit. When you record your answers, use the conventions described in the discussion section. Paste a copy of the pre-lab portion of the Lab Writeup Checklist into your hand-in materials. Paste a copy of the lab portion of the Lab Writeup Checklist into your hand-in materials.

Links to all files referenced in the lab and prelab can be found in the Files section at the end of this document.

The point of this exercise 74ls3374 to actually follow all the steps on the checklist, not just say you followed them. Assume that the output voltage is quiescent i. Pick an instruction where the exact execution time differs from the best case execution time and explain why in one sentence. For the questions in part B. Think of how embarrassed you will be if you get something wrong after saying you followed the checklist.

Refer above for details on wiring the circuit. Please see the course web page for due dates. Pin 2 provides D0 to bus, Pin 5 provides D1, etc. Assume the voltage drop across the LED is 1. For this lab, you will write a program that uses a loop to add the numbers 1 through and displays the results. Code files should be submitted separately, per the lab FAQ.

Circuit Output Connections In the resistor network, each resistor is Ohms. The term counter limit refers to the maximum value the counter runs datasheft e.

Your program shall meet the following requirements: Embedded Hardware – Part B: All non-code 74ls37 of the hand-in should be submitted as a single document.

Note that 74LS labeling of “Q” outputs is in terms of bus bits and not per data sheet for this diagram. Also, see the course materials repository page. And, as always, you must do the pre-labs independently.
