CE121L - Microprocessor System Design
Laboratory 3a
Week of February 3, 1997

In this lab, you will complete the memory system and run your program. Demonstrate it to the TA before next week's lab -- people who complete lab 3 late will receive half credit for this lab. People who have not completed lab 2/2a by early in this weeks lab will receive half credit for lab 2.

Prelab

1. Read the reference manual, especially sections 3 and 5, and the introduction to HC11 programming.
2. Read about the HC11's serial interface.
3. Prepare a test program that sends data, such as a repeated 1 or 2-character sequence out the serial interface at a slow baud rate, though the level converters.

Laboratory

1. Complete Laboratory 2.
2. If you have time, write in the level converter.
3. If you have time, run your test program, and use the scope to observe the signal coming out the serial port.
