5. Program/Load Device
Assuming the Port Setup settings are correct, press the “Ctrl+L” shortcut or click “Keyboard Controls” 
“Load Device” from the menu to program the device to the current state of the newly loaded LMK03806
file.
Figure 3: Loading the Device
Once the device has been initially loaded, CodeLoader will automatically program changed registers so it
is not necessary to re-load the device upon subsequent changes in the device configuration. It is possible
to disable this functionality by ensuring there is no checkmark by the “Options”  “AutoReload with
Changes.”
Because a default mode will be restored in the next step, this step isn’t really needed but included to
emphasize the importance of pressing “Ctrl+L” to load the device at least once after starting CodeLoader,
restoring a mode, or restoring a saved setup using the File menu.
See CodeLoader Usage or the CodeLoader 4 instructions located at http://www.ti.com/tool/codeloader

6. Restoring a Default Mode
Click “Mode”  “100 MHz XO/TCXO Reference”; then press Ctrl+L.
