4.10 NVM Re-Programming

Once the register settings are updated, the new values can be saved into the NVM by writing 0x0A to register address 0x34.

  • Figure 4-11 shows the button that saves the register settings into the NVM when using the TPS65219-GUI.
  • Table 4-24 shows the register field to be written when NOT using the TPS65219-GUI.

Note: It is recommended to export the selected register settings into a CSV and JSON file using the TPS65219-GUI. Figure 4-12 shows how to export the NVM settings. The file format must be selected on "Register File Format" before using the "Save Registers As".
