Figure 6. Clock Divider Settings
Note that clock pairs share the same dividers. This example also shows that Clocks 1, 4, 7, 8 and 9 are
powered down. These outputs are not used on the EVM.
4 EEPROM
Saving the custom configuration settings from the TSW4806 GUI (Figure 7) 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.
4.1 Writing to the EEPROM
Write to the EEPROM with the following steps:
(a) Configure the GUI to the desired setting.
(b) Select an address from 8 to 15 in the EEPROM section of the GUI.
(c) When the Write button is pushed, the current GUI settings are saved to the selected EEPROM
address.
Note: Read from the EEPROM by selecting the desired read address and pressing the Read button.
