1.4.5 Lab 6. Secondary to Primary Power Flow, Open Loop Check PWM Driver

This lab option is primarily provided as a focused test just for the PWM from a software perspective, so that the lab is run independent of the hardware connections of the reference design. With this lab the user can run the code on a C2000 controlCARD or LaunchPad™ just to observe the PWM waveforms.
