3. Program/Load Device

Press “Ctrl – L”

Assuming the Port Settings are correct, it is now

possible to click “Keyboard Controls”  “Load

Device” from the menu to program the device to the

current state of the newly loaded LMK01801 file. Ctrl-

L is the accelerator assigned to the Load Device option

and is very convenient.

Once the device has been loaded, by default

CodeLoader will automatically program changed

registers, so it is not necessary to load the device

again completely. It is possible to disable this functionality by ensuring there is no checkmark

by the “Options”  “AutoReload with Changes.”

Since 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 Appendix A: CodeLoader Usage or the CodeLoader 4 instructions located at

http://www.ti.com/tool/codeloader for more information on port setup. Appendix H:

Troubleshooting Information contains information on troubleshooting communications.

4. Restoring a Default Mode

Click “Mode”  “122.88 MHz VCXO Default”; then

Press “Ctrl – L”

Figure 6 – Setting the 122.88 MHz VCXO Default mode

For the purposes of this walkthrough a default mode will be loaded to ensure a common starting

point. This is important because when CodeLoader is closed, it remembers the last settings used

for a particular device. By loading the default mode a common starting point is ensured.

Loading a mode does not automatically program the device so it is necessary to press

“Ctrl – L” again to program the device.
