Lab 4 - Abstract 
Lab 4 - Abstract 
Lab 4 explores a variety of initialization tasks; the largest one being to setup the clocks for the 
MSP430. 
 
 
This lab also starts off with a worksheet where we will answer a number of questions (and write a 
little code) that will be used in the upcoming lab procedure. 
Lab 4a – Program MSP430 Clocks 
We explore the default clock rates for each of MSP430’s three internal clocks; then, set them up 
with a set of specified clock rates. 
(Extra) Lab 4b – Blink LED with Different Clocks  
If you have time, this lab provides an opportunity to explore the Watchdog Timer. 
(Extra) Lab 4C – Utilizing Crystals as Clock Sources 
Once again, if you have time, this lab gives us a chance to configure our system to use the 
external crystal oscillators found on the Launchpad.
