By default, the Smart Fuse Configurator is set to automatically persist when a change is made on the GUI interface. Likewise, when a fault occurs in the system or a tab page is changes, the GUI automatically pings the high-side switch controller for the latest configuration data and update accordingly. Change this behavior to a manual mode by selecting or deselecting the Settings then Auto-Persist/Refresh settings as Figure 4-13 shows. Note that "persist" refers to a write operation to the register configuration of the high-side switch and "refresh" refers to a reach from the register map of the high-side switch controller.

Once deselected, the device enters manual persist and refresh mode. This mode enables the corresponding button in the Settings menu. Once selected, these buttons initiate a manual refresh of the GUI (pinging the high-side switch for the latest data) or a manual persist of the settings. Note in manual refresh mode, the fault diagnostics are automatically set to manual refresh mode in the device settings tab.
