Try-Before-Buy Mode using the “Configuration” Tab
The PF3000FRDMPEVM comes with a PF3000 device whose OTP memory is pre-programmed. The PF3000 allows the user to override
the OTP memory using the "Try-Before-Buy" mode.
To use this mode, go to the "Configuration" tab and click on the "Enter TBB Mode" button in the top-right of the window. Use the drop down
options to change the voltage, sequence and configuration of the regulators. Click the "Update" button after all the desired options are
selected.
To restart the PF3000 using the selected configuration, click on the "Restart PMIC" button. Alternatively, you can toggle the PWRON button
to initiate the startup. The startup sequence can be monitored on an oscilloscope and will match this selection in the "Configuration" tab.
To measure voltages, use either a stand-alone meter or the on-board meters available in the GUI.
Use the "Save Configuration" and "Load Configuration" buttons to save the configuration for later use.
