Functional Description
3.10 Enabling Features and/or Configuration Settings Not Available in ClockBuilder Pro for Factory Pre-Programmed Devices
As with essentially all software utilities, ClockBuilder Pro is continuously updated and enhanced. By registering at http://
www.silabs.comand opting in for updates to software, you will be notified whenever changes are made and what the impact of those
changes are. This update process will ultimately enable ClockBuilder Pro users to access all features and register setting values docu-
mented in this data sheet and the Si5341/40 Family Reference Manual. However, if you must enable or access a feature or register
setting value so that the device starts up with this feature or a register setting, but the feature or register setting is NOT yet available in
CBPro, you must contact a Silicon Labs applications engineer for assistance. An example of this type of feature or custom setting is the
customizable amplitudes for the clock outputs. After careful review of your project file and custom requirements, a Silicon Labs applica-
tions engineer will email back your CBPro project file with your specific features and register settings enabled, using what is referred to
as the manual "settings override" feature of CBPro. "Override" settings to match your request(s) will be listed in your design report file.
Examples of setting "overrides" in a CBPro design report are shown below:
Table 3.3. Setting Overrides
Location

Once you receive the updated design file, simply open it in CBPro. After you create a custom OPN, the device will begin operation after
startup with the values in the NVM file, including the Silicon Labs-supplied override settings.
