Your program shall meet the following requirements: Assume that the output voltage is quiescent i. Be sure to 74l374 the Lab Writeup Checklist for both the prelab and lab writeup!

Think of how embarrassed you will be if you get something wrong datasyeet saying you followed the checklist. You will be expected to assemble, disassemble, and time code by hand on tests and quizzes. Put a brief comment at the beginning which describes the overall function of the code.

This lab uses the same circuit as Lab 2 part A. Embedded Hardware – Part B: Why is it valid or invalid? It is easy to make small mistakes when you are in a hurry. Machine code is fetched from memory and the instructions described are executed by the processor.

All non-code parts of the hand-in should be submitted as a single document.


For branch daatasheet, insert datashet at the appropriate locations and use the label values in your disassembled assembly code.

When you record your answers, use the conventions described in the discussion section. Paste a copy of the lab portion of the Lab Writeup Checklist into your hand-in materials. Note that 74LS labeling of “Q” outputs is in terms of bus bits and not per data sheet for this diagram. The first instruction is done as an example. This lab uses a flip-flop to hold a data value on dstasheet bar graph LED. 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.

Create a similar example using different, non-trivial e. Pick an instruction where the exact execution time differs from the best case execution time and explain why in one sentence.

For example, if Q7 is high, and Q6: We suggest each of the two students in your lab group be “in charge” of one of the two parts of the lab parts dattasheet help divide the work. To familiarize yourself with the microcontroller assembly instructions and the process of assembly.

Scan the printed-out document after you add the checkmarks and upload to the hand-in folder. Code files should be submitted separately, per the lab FAQ. You will connect the circuit and write a simple program to verify its operation. Assume the voltage drop across the LED is 1.


The term counter limit refers to the maximum value the counter runs to e. Circuit Output Connections In the resistor network, each resistor is Ohms. For this lab, you will write a program that uses a loop to add the numbers 1 through and displays the results.

It is OK to use CodeWarrior to check your work and make corrections after you have done it by hand. Please see the course web page for due dates. To familiarize you with the operation of the LS flip-flop and understand how it can be integrated into a circuit. And, as always, you must do the pre-labs independently. Demonstrate that you can read and understand the datasheet for an IC and use it in a circuit.

Limit your answer to 40 words. For the questions in part B. Look carefully at the data sheet!


Assume that all setup, hold, pulse duration, and propagation times are valid and the outputs have settled for these sample points. Also, see the course materials repository page.

For this lab, you will adapt the string hash program from lab 1.
