EEPROM
Saving the custom configuration settings from the TSW4806 GUI (
) is possible with the on-board
EEPROM. With the settings saved, the LMK04806 is programmed without using the GUI. The EEPROM
saves up to eight user-defined settings, starting from address 8. The EVM comes from the factory with two
pre-loaded configurations stored in address locations 0 and 1.
